Subject: DPP2: Do not include Protocol Version in Auth Req when testing v1
X-Git-Tag: hostap_2_10~1372
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=769139c490754b1963e86e5edf70760cb7350112;p=thirdparty%2Fhostap.git

DPP2: Do not include Protocol Version in Auth Req when testing v1

When DPP v2 implementation is hardcoded to behave as v1 for testing
purposes, leave out the Protocol Version attribute form Authentication
Request instead of including it there with indication for v1.
