wifi: mac80211: fix the comeback long retry times
BugLink: https://bugs.launchpad.net/bugs/2089340
[ Upstream commit 1524173a3745899612c71d9e83ff8fe29dbb2cfb ]
When we had a comeback, we will never use the default timeout values
again because comeback is never cleared.
Clear comeback if we send another association request which will allow
to start a default timer after Tx status.
The problem was seen with iwlwifi where the tx_status on the association
request is handled before the association response frame (which is the
usual case).
1) Tx assoc request 1/3
2) Rx assoc response (comeback, timeout = 1 second)
3) wait 1 second
4) Tx assoc request 2/3
5) Set timer to IEEE80211_ASSOC_TIMEOUT_LONG = 500ms (1 second after
round_up)
6) tx_status on frame sent in 4) is ignored because comeback is still
true
7) AP does not reply with assoc response
8) wait 1s <= This is where the bug is felt
9) Tx assoc request 3/3
With this fix, in step 6 we will reset the timer to
IEEE80211_ASSOC_TIMEOUT_SHORT = 100ms and we will wait only 100ms in
step 8.
