Subject: DPP: Add some more debug prints on GAS frame parsing errors
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7b962ef51337d79950ae6b72abbe03f1c9d1861;p=thirdparty%2Fhostap.git

DPP: Add some more debug prints on GAS frame parsing errors

These cases were referenced in a hwsim test case
dpp_hostapd_enrollee_gas_proto, but hostapd did not actually print the
matching strings into debug log.
