Subject: [PATCH] mac80211: fix sequence number allocation regression
|
|
|
|
The recent commit that moved around TX handlers dropped the sequence
|
|
number allocation at the end of ieee80211_tx_dequeue and calls
|
|
ieee80211_tx_h_sequence instead (for the non-fast-xmit case).
|
|
However, it did not change the fast-xmit sequence allocation condition
|
|
in ieee80211_xmit_fast_finish, which skipped seqno alloc if intermediate
|
|
tx queues are being used.
|
|
|
|
Drop the now obsolete condition.
|
|
|
|
Fixes: bb42f2d13ffc ("mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue")
