pull request: wireless-2.6 2010-08-16
From: John W. Linville
Date: Mon Aug 16 2010 - 16:44:46 EST
Dave,
This group of fixes is intended for 2.6.36. This includes a fix for a
warning backtrace related to pm_qos in ipw2100, a packet injection oops
for ath9k_htc, a connectivity regression for ath9k_htc related to HT
capabilities handling, a scanning regression in wl1251,
a firmware loading error in ath9k_htc, and a patch to disable L0s for
all ath5k cards (causes misc wierdness).
Please let me know if there are problems!
Thanks,
John
