[PATCH v2 0/3] mac80211: timeout tx agg sessions in way similar to rx agg sessions

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

 



  Currently tx aggregation is not being timed out even if timeout is
specified when aggregation is opened. Tx tid stays active until delba
arrives from recipient (i.e. recipient times out tid when it is
inactive).
  The problem with this approach is that delba can get lost in the air
and tx tid will stay perpetually opened on the originator while closed
on recipient thus all data sent via this tid will be lost.
 The problem manifests itself with connection becoming slow/unusable
with ping times jumping to 4s. At such time opened tx tid can be seen
on one side of the connection without corresponding rx tid one the
other side. This seems to be happening quite often soon after
connection on ar9102 I have.
  This patch implements tx tid timeouting in way very similar to rx tid
timeouting.

  All comments and suggestions are appreciated.
