The issue comes when there are multiple threads attempting to use the mailbox facility at the same time. The issue is the for the Virtual Function Driver, the only way to get the Virtual Interface statistics is to issue mailbox commands to ask the firmware for the VI Stats. And, because the VI Stats command can only retrieve a smallish number of stats per mailbox command, we have to issue three mailbox commands in quick succession. When ethtool or netstat command to get interface stats and interface up/down is run in a loop for every 0.1 sec, we observed mailbox collisions. And out of the two commands one would fail with the present code, since we don't queue the second command. To overcome the above issue, added a queue to access the mailbox. Whenever a mailbox command is issued add it to the queue. If its at the head issue the mailbox command, else wait for the existing command to complete. Usually command takes less than a milli-second to complete. Also timeout from the loop, if the command under execution takes long time to run. In reality, the number of mailbox access collisions is going to be very rare since no one runs such abusive script. Signed-off-by:

The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device. Signed-off-by:

Only set conntrack mark or labels when the commit flag is specified. This makes sure we can not set them before the connection has been persisted, as in that case the mark and labels would be lost in an event of an userspace upcall. OVS userspace already requires the commit flag to accept setting ct_mark and/or ct_labels. Validate for this in the kernel API. Signed-off-by:

With the upcoming support for cross-chip operations, it will be hard to distinguish portions of code supporting a single-chip or a switch fabric of interconnected chips. Make the code clearer now, by renaming the mv88e6xxx_priv_state chip structure to mv88e6xxx_chip. This patch brings no functional changes. Signed-off-by:

With the upcoming support for cross-chip operations and other mv88e6xxx enhancements, new files will be added. Similarly to mlxsw or b53, move mv88e6xxx files into their own folder. In the meantime, update the MAINTAINERS entry to please checkpatch.pl, by replacing the invalid 88E6352 entry with 88E6XXX, maintained by Andrew and myself. Signed-off-by:

Due to a typo we would always be using the MIB counter width of the first element of the counter array instead of the current element, and we would always be accessing the register statistics with a 64-bits read, while some could be 32-bits. This got unnoticed in testing with MDIO and SRAB which tolerate doing this, but testing with the SPI bus revealed bogus values being returned. Fix this by using the proper iterator here.

The commit f2a4d086 ("openvswitch: Add packet truncation support.") introduces packet truncation before sending to userspace upcall receiver. This patch passes up the skb->len before truncation so that the upcall receiver knows the original packet size. Potentially this will be used by sFlow, where OVS translates sFlow config header=N to a sample action, truncating packet to N byte in kernel datapath. Thus, only N bytes instead of full-packet size is copied from kernel to userspace, saving the kernel-to-userspace bandwidth. Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Preparation for IPv4 router Ido says: This series prepares the driver for IPv4 router support. The router follow-up patches are available at: https://github.com/jpirko/linux_mlxsw/tree/net-next_queue Patches 1-9 simplify the netdevice notification block and also add several checks during PRECHANGEUPPER events against topologies that aren't supported by the device. This will ensure L3 interfaces are only configured on top of valid netdevs. Patches 10-13 contain trivial changes required for the introduction of a generic FID struct - currently only used for vFIDs - in patch 14. Making the FID struct generic will allow us to easily associate the underlying FIDs with their L3-counterparts - Router interfaces (RIFs): FID Type | Used by | RIF Type -------------------------------------------------------- FID | The VLAN-aware bridge | VLAN vFID | VLAN-unaware bridges | FID rFID | non-bridged netdevs (follow-up) | Sub-port Obligatory ASCII art to visualize the above: A.B.C.D + | FID RIF + br0 E.F.G.H + + | | VLAN RIF +---------+---------+ + | | br1.W | vFID | + | | | vPort +-+-+ +-+-+ + swXpY.Z | | | | br1 +-+-+ +-+-+ + | | FID=W | | | +------------+------------+ | | | | +---+---+ +---+-+-+ +---+---+ | | | | | | | | | | | | | | | | | | +-------+ +-------+ +-------+ swXpY Patches 15-16 further generalize the struct by exploiting the fact that the FID is a shared resource among ports. Each FID type is assigned a 'leave' function that is invoked based on CHANGEUPPER events and takes care of the necessary clean-up. Patches 17-22 build upon the previous patches and use the FID struct for the VLAN-aware bridge and take care of cleaning up FID resources in the 'leave' functions. For now, these are only FDB records, but later on we'll have to remove the RIFs associated with these FIDs, which will in turn take care of routes and neighbours clean-up. The last patch adds debug prints that proved very useful during the development of this series. Tested with the existing L2 recipes: https://github.com/jpirko/lnst/tree/master/recipes/switchdev ==================== Signed-off-by:

There are situations in which a vPort is destroyed while still holding references to device's resources such as FIDs and FDB records. This can happen, for example, when a VLAN device is deleted while still being bridged. Instead of trying to make sure vPort destruction is invoked when it no longer uses device's resources, just free them upon destruction. This simplifies the code, as we no longer need to take different situations into account when events are received - cleanup is taken care of in one place. Signed-off-by:
