Subject: EAP-pwd peer: Allow fragmentation limit to be configured
X-Git-Tag: hostap_2_1~178
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=16a19ddae8aa696e7c3e5ac055958a469de9380f;p=thirdparty%2Fhostap.git

EAP-pwd peer: Allow fragmentation limit to be configured

The standard fragment_size network parameter can now be used to
configure EAP-pwd fragmentation limit instead of always using the
hardcoded value of 1020.
