[PATCH v9 0/2] mac80211: TXQ dequeue path rework

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is the ninth iteration of my attempts to reorder the TXQ dequeue
path to avoid issues with reorder-sensitive operations. This version is
split into two patches; the first one moves ieee80211_tx_dequeue() to
avoid adding function stubs at the top of tx.c.

Changes since v8:
- Don't add function stubs to the beginning of tx.c
- Don't use control.hw_key from the dequeued packet, since that can go
  away while the packet is queued. Instead, run the select_key handler
  on dequeue and use the key from that.
- Change places that check tin.backlog_packets as an indication of
  whether the TXQ has anything queued to also look at the 'frags' queue.
- Don't change the order of the select_key handler with respect to the
  other handlers.
- Rebase on current mac80211-next tree.
