Subject: nl80211: Provide subtype and reason code for AP SME drivers
X-Git-Tag: hostap_2_4~1363
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59d7148ad7ce915be22388bea441cffc39ab91a4;p=thirdparty%2Fhostap.git

nl80211: Provide subtype and reason code for AP SME drivers

This allows drivers that implement AP SME internally to generate a
Deauthentication or Disassociation frame with the specified reason code.
This was already done with drivers that use hostapd/wpa_supplicant for
AP SME.
