Subject: Debug print on CONFIG_NO_TKIP=y prevent RSNE with TKIP as group cipher
X-Git-Tag: hostap_2_11~2127
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0c88d1487cfd2643bf206541884d63869da7a4a3;p=thirdparty%2Fhostap.git

Debug print on CONFIG_NO_TKIP=y prevent RSNE with TKIP as group cipher

This makes the debug log clearer for one of the more likely cases of
"invalid group cipher" preventing RSNE parsing.
