Subject: ath9k_htc: Fix WMI and beacon header
X-Git-Tag: v3.0-rc2~7^2~16^2~420
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1c165c972b040f9ce199b8d8d3cc4f619872cba5;p=platform%2Fkernel%2Flinux-3.10.git

ath9k_htc: Fix WMI and beacon header

Match the beacon header with that of the firmware.
Also, the firmware reports the TSF for an SWBA, so
store it.
