This is helpful for e.g. draining per-driver (not per-port) tagger queues. Signed-off-by: Vladimir Oltean <olteanv@gmail.com> --- Changes in v3: Moved after dsa_switch_unregister_notifier, which is symmetrical to where the setup callback is. Changes in v2: Patch is new. include/net/dsa.h | 1 + net/dsa/dsa2.c | 3 +++ 2 files changed, 4 insertions(+)
