[PATCH net 0/3] net/mlx5: LAG bug fixes

[Tariq Toukan]

Hi,

Three bug fixes by Shay in the mlx5 LAG subsystem.

Patch 1 fixes an off-by-one in the error rollback path of
mlx5_lag_create_single_fdb(): the loop started from the failed index i,
potentially operating on uninitialized state or double-tearing-down an
entry that had already self-rolled-back. The rollback should start from
i - 1.

Patch 2 fixes a hang in mlx5_mpesw_work(): when
mlx5_lag_get_devcom_comp() returns NULL the function returned early
without calling complete(), blocking any caller waiting on mpesww->comp
indefinitely.

Patch 3 fixes a kernel crash during teardown when mlx5_lag_get_dev_seq()
returns an error because no device is marked as master or the peer is no
longer in the LAG. The peer flow cleanup is now skipped instead of
proceeding with a bad pointer.

Regards,
Tariq
