Subject: [PATCH] wifi: mac80211: do not drop packets smaller than the
|
|
LLC-SNAP header on fast-rx
|
|
|
|
Since STP TCN frames are only 7 bytes, the pskb_may_pull call returns an error.
|
|
Instead of dropping those packets, bump them back to the slow path for proper
|
|
processing.
|
|
|
|
Fixes: 49ddf8e6e234 ("mac80211: add fast-rx path")
