Subject: hostapd: Clear WLAN_STA_ASSOC_REQ_OK if sending the assoc response failed
X-Git-Tag: hostap_2_0~214
X-Git-Url: http://www.project-moonshot.org/gitweb/?a=commitdiff_plain;h=22b42372d081eb8e310742f718ebe9abcfacb51c;p=mech_eap.git

hostapd: Clear WLAN_STA_ASSOC_REQ_OK if sending the assoc response failed

As long as WLAN_STA_ASSOC_REQ_OK is set in sta->flags, Class 3 frames do
not trigger a disassoc/deauth. If it is still set even after the assoc
response tx has already failed, it may take somewhat longer for clients
to realize that the connection wasn't fully established.
