Subject: mac80211: share sta_info->ht_info
X-Git-Tag: v2.6.28-rc1~717^2~268^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=687c7c0807371aeaa94ff2fff511eeb326b5c5de;p=profile%2Fivi%2Fkernel-x86-ivi.git

mac80211: share sta_info->ht_info

Rate control algorithms may need access to a station's
HT capabilities, so share the ht_info struct in the
public station API.
