2012-05-16mac80211: fix TX aggregation session timerJohannes Berg1-2/+8
In commit 12d3952fc4a1cd96234bc7023bf7eefeb0bb6355 ("mac80211: optimize aggregation session timeout handling") two bugs were introduced: 1) RCU usage was completely broken since no locks are held 2) the timer must not rearm when agg session is stopping Reported-and-tested-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-05-16mac80211: fix single queue driversJohannes Berg1-1/+3
My queue management rework broke drivers that don't have multiple AC queues and register a single queue only, causing a warning: WARNING: at net/mac80211/iface.c:162 ieee80211_check_queues This was due to filling the queues wrongly and then noticing the error when checking later.

2012-05-16bcma: Move initialization of SPROM to prevent overwriteNathan Hintz2-2/+4
The first thing bcm47xx_fill_sprom does is initialize (zero fill) the SPROM. For BCMA SOC, this wipes out any values previously read by bcm47xx_fill_sprom_ethernet (see arch/mips/bcm47xx/setup.c - bcm47xx_get_sprom_bcma). Move the initialization of SPROM so it is called prior to filling in any values. Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

The devices I know of are not using a PCIe core with rev <= 10. The BCM4718 uses a PCIe core with revision 14 and the BCM43224 uses a PCIe core with revision 15.
