From ca14405e3b25b38221d027d8970c1d74ed0b6532 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Wed, 8 Oct 2014 08:43:19 +0530 Subject: ath9k: Fix sequence number assignment Currently, ath9k uses a global counter for all frames that need to be assigned a sequence number. QoS-data frames are handled properly since they have a per-tid counter. But, beacons and other management frames use the same counter even if multiple interfaces or contexts are present. Fix this issue by making the counter per-interface and using it when mac80211 sets IEEE80211_TX_CTL_ASSIGN_SEQ. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
