Subject: P2P: Indicate reason=UNAVAILABLE for group netdev going down
X-Git-Tag: hostap_2_4~496
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f2cf379233bf4e8fc5580c7a03858a7b5581368;p=thirdparty%2Fhostap.git

P2P: Indicate reason=UNAVAILABLE for group netdev going down

There is a race condition between receiving an AP stopped event and
netdev down event. These resulted in different group removal reasons on
a GO device (UNAVAILABLE for stop AP event coming first and REQUESTED
for netdev event first). Make this more consistent by reporting
UNAVAILABLE for both possible cases.
