Subject: P2P: Consider 5 GHz channels also for auto GO
X-Git-Tag: hostap_2_4~46
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=95d7b863ecab973bb0829e038c0548c1b934d96b;p=thirdparty%2Fhostap.git

P2P: Consider 5 GHz channels also for auto GO

When there is no channel preference mentioned by user, auto GO
can be started on any of the 5 GHz channels supported for P2P.
Consider operating classes 115 and 124 which do not require DFS.
