| H A D | en_tc.c | 6a06c2f7 Sat Aug 03 13:43:06 CDT 2019 Vlad Buslov <vladbu@mellanox.com> net/mlx5e: Refactor neigh used value update for concurrent execution
In order to remove dependency on rtnl lock and allow neigh used value
update workqueue task to execute concurrently with tc, refactor
mlx5e_tc_update_neigh_used_value() for concurrent execution:
- Lock encap table when accessing encap entry to prevent concurrent
changes.
- Save offloaded encap flows to temporary list and release them after encap
entry is updated. Add mlx5e_put_encap_flow_list() helper which is
intended to be shared with neigh update code in following patch in this
series. This is necessary because mlx5e_flow_put() can't be called while
holding encap_tbl_lock.
