Currently if the driver registers devlink port instance, he should set the devlink port attributes as well. Then the devlink core is able to obtain switch id itself, no need for driver to implement the ndo. Once all drivers will implement devlink port registration, this ndo should be removed. This warning guides new drivers to do things as they should be done. Signed-off-by:

Currently the switch_id is being only initialized when switching eswitch mode from "legacy" to "switchdev". However, nothing prevents the id to be initialized from the very beginning. Physical ports can show it even in "legacy" mode. Signed-off-by:

Introduce devlink_compat_switch_id_get() helper which fills up switch_id according to passed netdev pointer. Call it directly from dev_get_port_parent_id() as a fallback when ndo_get_port_parent_id is not defined for given netdev. Signed-off-by:

Extend devlink_port_attrs_set() to pass switch ID for ports which are part of switch and store it in port attrs. For other ports, this is NULL. Note that this allows the driver to group devlink ports into one or more switches according to the actual topology. Signed-off-by:

We can optimize the fdb convergence when a backup_port is present by not immediately flushing the entries of the stopped port since traffic for those entries will flow towards the backup_port. There are 2 cases specifically that benefit most: - when the stopped port comes up before the entries expire by themselves - when there's an external entry refresh and they're kept while the backup_port is operating (e.g. mlag) Signed-off-by:

Recent changes to TC flower remove the requirement for rtnl lock when accessing and modifying filters. Refcounts now ensure access and deletion do not happen concurrently. However, the reoffload function which cycles through all filters and replays them to registered hw drivers is not protected. Use the fl_get_next_filter() function to cycle the filters for reoffload and ensure the ref taken by this function is put when done with each filter. Signed-off-by:

Simplify this code by updating bridge multicast stats from maybe_deliver(). Note that commit 6db6f0ea ("bridge: multicast to unicast"), in case the port flag BR_MULTICAST_TO_UNICAST is set, never updates the previous port pointer, therefore it is always going to be different from the existing port in this deduplicated list iteration.

The function hnae3_match_n_instantiate() was called both by initializing or uninitializing client. For uninitializing, the return value was never used. To make it more clear, this patch splits it to two functions, hnae3_init_client_instance() and hnae3_uninit_client_instance(). Signed-off-by:

When set 2 same MAC to different function of one port, IMP will return error as the later one may modify the origin one. This will cause bond fail for 2 VFs of one port. Driver just print warning and return 0 with this patch, so if set same MAC address, it will return 0 but do not really configure HW. Signed-off-by:

When the kdump kernel started, the HNS3 driver fail to register: [14.753340] hns3 0000:7d:00.0: Alloc umv space failed, want 512, get 0 [14.795034] hns3 0000:7d:00.0: add uc mac address fail, ret =-22. By default, the HNS3 driver will use about 512M memory, but usually the reserved memory of kdump kernel is 576M, so the HNS3 driver fail to register. This patch reduces the memory use in kdump kernel to about 16M. And when the kdump kernel starts, we must clear ucast mac address first to avoid add fail. Signed-off-by:

David Ahern says: ==================== net: More movement to fib_nh_common Second set of three with the end goal of enabling IPv6 gateways with IPv4 routes. This set moves: - the ipv4 tracepoint to take a fib_nh_common and updates it to handle a v6 gateway. - consolidates route notifications to use the same fill functions for both ipv4 and ipv6 v4 - enhanced the commit message for patches 1 and 2 v3 - comments from Martin: + renamed FIB_RES_NH to FIB_RES_NHC + removed family check from fib_result_prefsrc + in fib_nexthop_info, renamed nexthop arg to nhc and dropped for_ipv4 arg v2 - dropped patches moving cached routes and exception buckets to fib_nh_common. The goal is allowing a fib6_nh to be used with an IPv4 route. The hold up is the need for separate exception buckets - one for v6 routes and one for v4 routes. When all of the nexthop patches are in, adding a secondi exception bucket pushes IPv6 fib6_info allocations over 256 which means fib6_info allocations roll up to 512. Hence, deferring the patches until some data mining can be done to keep the allocations at 256. ==================== Acked-by:
