This change adds a 'type' attribute to routes, which can be parsed from a RTM_NEWROUTE message. This will help to distinguish local vs. peer routes in a future change. This means userspace will need to set a correct rtm_type in RTM_NEWROUTE and RTM_DELROUTE messages; we currently only accept RTN_UNICAST. Signed-off-by:

Currently, four reset types are supported for the HNS3 ethernet driver: IMP reset, global reset, function reset, and FLR. Only FLR can now be triggered by the user. To restore the device when an exception occurs, add support for triggering reset by ethtool. Run the "ethtool --reset DEVNAME mgmt | all | dedicated" to trigger the IMP | global | function reset manually. In addition, VF can only trigger function reset. Signed-off-by:

There seems to be no reason to have different error messages between netlink and printk. It also cleans up the function slightly. Signed-off-by:

All of the symbols either only exist in bond_options.c or nowhere at all. These symbols were verified to not exist in the code base by using `git grep` and their removal was verified by compiling bonding.ko. Signed-off-by:

The ocelot driver makes use of regmap, wrapping it with driver specific operations that are thin wrappers around the core regmap APIs. These are exported with EXPORT_SYMBOL, dropping the _GPL from the core regmap exports which is frowned upon. Add _GPL suffixes to at least the APIs that are doing register I/O. Signed-off-by:

Vladimir Oltean says: ==================== DSA tagger helpers The goal of this series is to minimize the use of memmove and skb->data in the DSA tagging protocol drivers. Unfiltered access to this level of information is not very friendly to drive-by contributors, and sometimes is also not the easiest to review. For starters, I have converted the most common form of DSA tagging protocols: the DSA headers which are placed where the EtherType is. The helper functions introduced by this series are: - dsa_alloc_etype_header - dsa_strip_etype_header - dsa_etype_header_pos_rx - dsa_etype_header_pos_tx This series is just a resend as non-RFC of v1. ==================== Signed-off-by:David S.

It seems that protocol tagging driver writers are always surprised about the formula they use to reach their EtherType header on RX, which becomes apparent from the fact that there are comments in multiple drivers that mention the same information. Create a helper that returns a void pointer to skb->data - 2, as well as centralize the explanation why that is the case. Signed-off-by:

Hide away the memmove used by DSA EtherType header taggers to shift the MAC SA and DA to the left to make room for the header, after they've called skb_push(). The call to skb_push() is still left explicit in drivers, to be symmetric with dsa_strip_etype_header, and because not all callers can be refactored to do it (for example, brcm_tag_xmit_ll has common code for a pre-Ethernet DSA tag and an EtherType DSA tag).

Vladimir Oltean authored
All header taggers open-code a memmove that is fairly not all that obvious, and we can hide the details behind a helper function, since the only thing specific to the driver is the length of the header tag. Signed-off-by:

Parav Pandit says: ==================== devlink: Control auxiliary devices Currently, for mlx5 multi-function device, a user is not able to control which functionality to enable/disable. For example, each PCI PF, VF, SF function by default has netdevice, RDMA and vdpa-net devices always enabled. Hence, enable user to control which device functionality to enable/disable. This is achieved by using existing devlink params [1] to enable/disable eth, rdma and vdpa net functionality control knob. For example user interested in only vdpa device function: performs, $ devlink dev param set pci/0000:06:00.0 name enable_rdma value false \ cmode driverinit $ devlink dev param set pci/0000:06:00.0 name enable_eth value false \ cmode driverinit $ devlink dev param set pci/0000:06:00.0 name enable_vnet value true \ cmode driverinit $ devlink dev reload pci/0000:06:00.0 Reload command honors parameters set, initializes the device that user has composed using devlink dev params and resources. Devices before reload: mlx5_core.sf.4 (subfunction device) /\ /| \ / | \ / | \ mlx5_core.eth.4 | mlx5_core.rdma.4 (SF eth aux dev) | (SF rdma aux dev) | | | | | | enp6s0f0s88 | mlx5_0 (SF netdev) | (SF rdma device) | mlx5_core.vnet.4 (SF vnet aux dev) | | auxiliary/mlx5_core.sf.4 (vdpa net mgmt device) Above example reconfigures the device with only VDPA functionality. Devices after reload: mlx5_core.sf.4 (subfunction device) /\ / \ / \ / \ mlx5_core.vnet.4 no eth, no rdma aux devices (SF vnet aux dev) Above parameters enable user to compose the device as needed based on the use case. Since devlink params are done on the devlink instance, these knobs are uniformly usable for PCI PF, VF and SF devices. ==================== Signed-off-by: -

Parav Pandit authored
Currently device configuration parameters can be registered as an array. Due to this a constant array must be registered. A single driver supporting multiple devices each with different device capabilities end up registering all parameters even if it doesn't support it. One possible workaround a driver can do is, it registers multiple single entry arrays to overcome such limitation. Better is to provide a API that enables driver to register/unregister a single parameter. This also further helps in two ways. (1) to reduce the memory of devlink_param_entry by avoiding in registering parameters which are not supported by the device. (2) avoid generating multiple parameter add, delete, publish, unpublish, init value notifications for such unsupported parameters Signed-off-by:

Nikolay Aleksandrov says: ==================== net: bridge: vlan: add global mcast options This is the first follow-up set after the support for per-vlan multicast contexts which extends global vlan options to support bridge's multicast config per-vlan, it enables user-space to change and dump the already existing bridge vlan multicast context options. The global option patches (01 - 09 and 12-13) follow a similar pattern of changing current mcast functions to take multicast context instead of a port/bridge directly. Option equality checks have been added for dumping vlan range compression. The last 2 patches extend the mcast router dump support so it can be re-used when dumping vlan config. patches 01 - 09: add support for various mcast options patches 10 - 11: prepare for per-vlan querier control patches 12 - 13: add support for querier control and router control patches 14 - 15: add support for dumping per-vlan router ports Next patch-sets: - per-port/vlan router option config - iproute2 support for all new vlan options - selftests ==================== Signed-off-by: -

Embed the standard multicast router port export by br_rports_fill_info() into a new global vlan attribute BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS. In order to have the same format for the global bridge mcast context and the per-vlan mcast context we need a double-nesting: - BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS - MDBA_ROUTER Currently we don't compare router lists, if any router port exists in the bridge mcast contexts we consider their option sets as different and export them separately. In addition we export the router port vlan id when dumping similar to the router port notification format. Signed-off-by:

Alex Elder says: ==================== net: ipa: use runtime PM reference counting This series does further rework of the IPA clock code so that we rely on some of the core runtime power management code (including its referencing counting) instead. The first patch makes ipa_clock_get() act like pm_runtime_get_sync(). The second patch makes system suspend occur regardless of the current reference count value, which is again more like how the runtime PM core code behaves. The third patch creates functions to encapsulate all hardware suspend and resume activity. The fourth uses those functions as the ->runtime_suspend and ->runtime_resume power callbacks. With that in place, ipa_clock_get() and ipa_clock_put() are changed to use runtime PM get and put functions when needed. The fifth patch eliminates an extra clock reference previously used to control system suspend. The sixth eliminates the "IPA clock" reference count and mutex. The final patch replaces the one call to ipa_clock_get_additional() with a call to pm_runtime_get_if_active(), making the former unnecessary. ==================== Signed-off-by: -
