From f3f66b69c8ff08b46975d9e99c7ecb92a8b12eda Mon Sep 17 00:00:00 2001 From: Christian Lamparter <chunkeey@googlemail.com> Date: Mon, 4 Jan 2010 00:52:56 +0100 Subject: [PATCH] mac80211: fix ampdu_action tx_start ssn The start_seq_num is taken from the station's tid_seq[tid]. This is fine, except tid_seq sequence counter is shifted by 4 bits to accommodate for frame fragmentation. Both (iwlagn & ath9k) were unaffected by this minor glitch, because they don't read the *ssn for the AMPDU_TX_START action.
