Subject: Allow BSS to return information for AP that uses an invalid WSC IE
X-Git-Tag: hostap_2_5~91
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc078be2dd7ff99d03c2edf88a1c226e151d00b0;p=thirdparty%2Fhostap.git

Allow BSS to return information for AP that uses an invalid WSC IE

Previously, the BSS command returned an error if the WSC IE(s) in scan
results could not be parsed. This may be not ideal for all cases, to
instead of rejecting the command completely, return all other
information apart from the WPS information in such a case.
