Subject: Always reply to MTU probes via UDP.
X-Git-Tag: release-1.0.11~9
X-Git-Url: https://www.tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=a8f7fccbc2b5f1c4c39fc2804abaa358b31a5080;ds=sidebyside

Always reply to MTU probes via UDP.

It could sometime happen that a node would return MTU probes via TCP, which
does not make a lot of sense.
