Subject: wlantest: Do not report decryption failures for WEP keys if no keys
X-Git-Tag: hostap_2_10~1489
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=866c3acb8cce8806d0b40393a407347e1b9add32;p=thirdparty%2Fhostap.git

wlantest: Do not report decryption failures for WEP keys if no keys

If no WEP keys are available, there is not going to be an attempt to
decrypt the frame, so don't claim decryption failed.
