Subject: tests: Convert binascii.hexlify() output to a string object for python3
X-Git-Tag: hostap_2_8~473
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ab74770e730d7e223007d35bda052b8228afa83;p=thirdparty%2Fhostap.git

tests: Convert binascii.hexlify() output to a string object for python3

This is needed in cases the hexlify() output is used to concatenate with
a string or used in string comparisons.
