Subject: HT: Skip ht_capab validation if ieee80211n=0
X-Git-Tag: hostap-1-bp~488
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ec2b89098168ee6aade616ed9e2bad7a2d8eb27c;p=thirdparty%2Fhostap.git

HT: Skip ht_capab validation if ieee80211n=0

There is no point in running through the 40 MHz scan if HT is
actually disabled regardless of whether the ht_capab parameter
is set.
