From 50ea05efaf3bed7dd34bcc2635a8b3f53bd0ccc1 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Wed, 30 Dec 2015 16:06:04 +0200 Subject: [PATCH] mac80211: pass block ack session timeout to to driver Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.
