Subject: wl12xx: AP-mode - set STA HT capabilities when adding a STA
X-Git-Tag: next-20110830~51^2~79^2~12
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b932ab9f156488a56577873b638ecb1e65fa8d7;p=karo-tx-linux.git

wl12xx: AP-mode - set STA HT capabilities when adding a STA

In addition, set global HT operation mode via ACX_HT_BSS_OPERATION when
a change is detected by usermode
