Subject: staging: rtl8723au: OnDeAuth23a() use ieee80211 header defines
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=be47f78295eca082f8263aaba8ad7d5ab5e865fd;p=openwrt%2Fstaging%2Fblogic.git

staging: rtl8723au: OnDeAuth23a() use ieee80211 header defines

Use the proper ieee80211.h structs to parse the response instead of
hard coded offsets.
