Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-01-09 This series contains updates to ixgbe and ixgbevf only. Emil fixes an issue with "wake on LAN"(WoL) where we need to ensure we enable the reception of multicast packets so that WoL works for IPv6 magic packets. Cleaned up code no longer needed with the update to adaptive ITR. Paul update the driver to advertise the highest capable link speed when a module gets inserted. Also extended the displaying of firmware version to include the iSCSI and OEM block in the EEPROM to better identify firmware versions/images. Tonghao Zhang cleans up a code comment that no longer applies since InterruptThrottleRate has been removed from the driver. Alex fixes SR-IOV and MACVLAN offload interaction, where the MACVLAN offload was incorrectly configuring several filters with the wrong pool value which resulted in MACLVAN interfaces not being able to receive traffic that had to pass over the physical interface. Fixed transmit hangs and dropped receive frames when the number of VFs changed. Added support for RSS on MACVLAN pools for X550 devices. Fixed up the MACVLAN limitations so we can now support 63 offloaded devices. Cleaned up MACVLAN code that is no longer needed with the recent changes and fixes. ==================== Signed-off-by:

Heiner Kallweit says: ==================== r8169: improve runtime pm On my system with two network ports I found that runtime PM didn't suspend the unused port. Therefore I checked runtime pm in this driver in somewhat more detail and this series improves runtime pm in general and solves the mentioned issue. Tested on a system with RTL8168evl (MAC version 34). ==================== Signed-off-by: -

So far rpm doesn't cover cases like unused ports which are never brought up. If they are active at probe time they remain in this state. Included in this patch: - Let the idle notification check whether we can suspend and let it schedule the suspend. This way we don't need to have calls to pm_schedule_suspend in different places. - At the end of rtl_open and rtl_init_one send an idle notification to allow suspending if the link is down. If a cable is plugged in aneg is finished before the suspend timer expires and the suspend request is cancelled. - Change rtl8169_runtime_suspend to power down the chip if the interface is down. Successfully tested on a RTL8168evl (mac version 34). Signed-off-by:

This patch partially reverts commit e4fbce74 "r8169: Fix runtime power management" from 2010. At that time the suspend delay was 100ms and therefore suspending happened during initial aneg. Currently suspend delay is 5s, so suspend starts after aneg and the issue doesn't exist any longer. On my system aneg takes almost 3s, to be on the safe side let's increase the suspend delay to 10s.

The current criteria for returning POLLOUT from a group member socket is too simplistic. It basically returns POLLOUT as soon as the group has external destinations, something obviously leading to a lot of spinning during destination congestion situations. At the same time, the internal congestion handling is unnecessarily complex. We now change this as follows. - We introduce an 'open' flag in struct tipc_group. This flag is used only to help poll() get the setting of POLLOUT right, and *not* for congeston handling as such. This means that a user can choose to ignore an EAGAIN for a destination and go on sending messages to other destinations in the group if he wants to. - The flag is set to false every time we return EAGAIN on a send call. - The flag is set to true every time any member, i.e., not necessarily the member that caused EAGAIN, is removed from the small_win list. - We remove the group member 'usr_pending' flag. The size of the send window and presence in the 'small_win' list is sufficient criteria for recognizing congestion. This solution seems to be a reasonable compromise between 'anycast', which is normally not waiting for POLLOUT for a specific destination, and the other three send modes, which are. Acked-by:

When a member joins a group, it also indicates a binding scope. This makes it possible to create both node local groups, invisible to other nodes, as well as cluster global groups, visible everywhere. In order to avoid that different members end up having permanently differing views of group size and memberhip, we must inhibit locally and globally bound members from joining the same group. We do this by using the binding scope as an additional separator between groups. I.e., a member must ignore all membership events from sockets using a different scope than itself, and all lookups for message destinations must require an exact match between the message's lookup scope and the potential target's binding scope. Apart from making it possible to create local groups using the same identity on different nodes, a side effect of this is that it now also becomes possible to create a cluster global group with the same identity across the same nodes, without interfering with the local groups.

Currently, when a user is subscribing for binding table publications, he will receive a PUBLISH event for all already existing matching items in the binding table. However, a group socket making a subscriptions doesn't need this initial status update from the binding table, because it has already scanned it during the join operation. Worse, the multiplicatory effect of issuing mutual events for dozens or hundreds group members within a short time frame put a heavy load on the topology server, with the end result that scale out operations on a big group tend to take much longer than needed. We now add a new filter option, TIPC_SUB_NO_STATUS, for topology server subscriptions, so that this initial avalanche of events is suppressed. This change, along with the previous commit, significantly improves the range and speed of group scale out operations. We keep the new option internal for the tipc driver, at least for now. Acked-by:

When a socket is joining a group, we look up in the binding table to find if there are already other members of the group present. This is used for being able to return EAGAIN instead of EHOSTUNREACH if the user proceeds directly to a send attempt. However, the information in the binding table can be used to directly set the created member in state MBR_PUBLISHED and send a JOIN message to the peer, instead of waiting for a topology PUBLISH event to do this. When there are many members in a group, the propagation time for such events can be significant, and we can save time during the join operation if we use the initial lookup result fully. In this commit, we eliminate the member state MBR_DISCOVERED which has been the result of the initial lookup, and do instead go directly to MBR_PUBLISHED, which initiates the setup. After this change, the tipc_member FSM looks as follows: +-----------+ ---->| PUBLISHED |-----------------------------------------------+ PUB- +-----------+ LEAVE/WITHRAW | LISH |JOIN | | +-------------------------------------------+ | | | LEAVE/WITHDRAW | | | | +------------+ | | | | +----------->| PENDING |---------+ | | | | |msg/maxactv +-+---+------+ LEAVE/ | | | | | | | | WITHDRAW | | | | | | +----------+ | | | | | | | |revert/maxactv| | | | | | | V V V V V | +----------+ msg +------------+ +-----------+ +-->| JOINED |------>| ACTIVE |------>| LEAVING |---> | +----------+ +--- -+------+ LEAVE/+-----------+DOWN | A A | WITHDRAW A A A EVT | | | |RECLAIM | | | | | |REMIT V | | | | | |== adv +------------+ | | | | | +---------| RECLAIMING |--------+ | | | | +-----+------+ LEAVE/ | | | | |REMIT WITHDRAW | | | | |< adv | | | |msg/ V LEAVE/ | | | |adv==ADV_IDLE+------------+ WITHDRAW | | | +-------------| REMITTED |------------+ | | +------------+ | |PUBLISH | JOIN +-----------+ LEAVE/WITHDRAW | ---->| JOINING |-----------------------------------------------+ +-----------+ Acked-by: -

After the changes in the previous commit the group LEAVE sequence can be simplified. We now let the arrival of a LEAVE message unconditionally issue a group DOWN event to the user. When a topology WITHDRAW event is received, the member, if it still there, is set to state LEAVING, but we only issue a group DOWN event when the link to the peer node is gone, so that no LEAVE message is to be expected.

In the current implementation, a group socket receiving topology events about other members just converts the topology event message into a group event message and stores it until it reaches the right state to issue it to the user. This complicates the code unnecessarily, and becomes impractical when we in the coming commits will need to create and issue membership events independently. In this commit, we change this so that we just notice the type and origin of the incoming topology event, and then drop the buffer. Only when it is time to actually send a group event to the user do we explicitly create a new message and send it upwards. Acked-by:

We handle a corner case in the function tipc_group_update_rcv_win(). During extreme pessure it might happen that a message receiver has all its active senders in RECLAIMING or REMITTED mode, meaning that there is nobody to reclaim advertisements from if an additional sender tries to go active. Currently we just set the new sender to ACTIVE anyway, hence at least theoretically opening up for a receiver queue overflow by exceeding the MAX_ACTIVE limit. The correct solution to this is to instead add the member to the pending queue, while letting the oldest member in that queue revert to JOINED state. In this commit we refactor the code for handling message arrival from a JOINED member, both to make it more comprehensible and to cover the case described above. Acked-by:

Tariq Toukan says: ==================== ethtool ringparam upper bound This patchset by Jenny adds sanity checks in ethtool ringparam operation for input upper bounds, similarly to what's done in ethtool_set_channels. The checks are added in patch 1, using a call to get_ringparam prior to calling set_ringparam NDO. Patch 2 changes the function's behavior in mlx4_en, so that it returns an error for out-of-range input, instead of rounding it to closest valid, similar to mlx5e. Patch 3 removes the upper bound checks in mlx5e_ethtool_set_ringparam as it becomes redundant.

The l2 acceleration private pointer isn't needed in the ring struct. It isn't really used anywhere other than to test and see if we are supporting an offloaded macvlan netdev, and it is much easier to test netdev for not being ixgbe based to verify that. Signed-off-by:

This patch simplifies the check for Tx pending traffic and makes it more holistic as there being any difference between next_to_use and next_to_clean is much more informative than if head and tail are equal, as it is possible for us to either not update tail, or not be notified of completed work in which case next_to_clean would not be equal to head. In addition the simplification makes it so that we don't have to read hardware which allows us to drop a number of variables that were previously being used in the call. Signed-off-by:

This change is a fix of the macvlan offload so that we correctly handle macvlan offloaded devices. Specifically we were configuring our limits based on the assumption that we were going to max out the RSS indices for every mode. As a result when we went to 15 or more macvlan interfaces we were forced into the 2 queue RSS mode on VFs even though they could have still supported 4. This change splits the logic up so that we limit either the total number of macvlan instances if DCB is enabled, or limit the number of RSS queues used per macvlan (instead of per pool) if SR-IOV is enabled. By doing this we can make best use of the part. In addition I have increased the maximum number of supported interfaces to 63 with one queue per offloaded interface as this more closely reflects the actual values supported by the interface.

The num_rx_pools value is overwritten when we reinitialize the queue configuration. In reality we shouldn't need to be updating the value since it is redone every time we call into ixgbe_setup_tc so for now just drop the spots where we were incrementing or decrementing the value. Signed-off-by:

In order for RSS to work on the macvlan pools of the X550 we need to populate the MRQC, RETA, and RSS key values for each pool. This patch makes it so that we now take care of that. In addition I have dropped the macvlan specific configuration of psrtype since it is redundant with the code that already exists for configuring this value. Signed-off-by:

If the number of VFs are changed we need to reinitialize the part since the offset for the device and the number of pools will be incorrect. Without this change we can end up seeing Tx hangs and dropped Rx frames for incoming traffic. In addition we should drop the code that is arbitrarily changing the default pool and queue configuration. Instead we should wait until the port is reset and reconfigured via ixgbe_sriov_reinit.

When SR-IOV was enabled the macvlan offload was configuring several filters with the wrong pool value. This would result in the macvlan interfaces not being able to receive traffic that had to pass over the physical interface. To fix it wrap the pool argument in the VMDQ_P macro which will add the necessary offset to get to the actual VMDq pool Signed-off-by:

The ability to set speed and duplex for virtio_net is useful in various scenarios as described here: 16032be5 virtio_net: add ethtool support for set and get of settings However, it would be nice to be able to set this from the hypervisor, such that virtio_net doesn't require custom guest ethtool commands. Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows the hypervisor to export a linkspeed and duplex setting. The user can subsequently overwrite it later if desired via: 'ethtool -s'. Note that VIRTIO_NET_F_SPEED_DUPLEX is defined as bit 63, the intention is that device feature bits are to grow down from bit 63, since the transports are starting from bit 24 and growing up.
