Subject: Send large packets we cannot handle properly via TCP.
X-Git-Tag: release-1.0.10~22
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=b5ccce296848aab72d574ca3de14af5fdf3efa4d;hp=b5ccce296848aab72d574ca3de14af5fdf3efa4d

Send large packets we cannot handle properly via TCP.

During the path MTU discovery phase, we might not know the maximum MTU yet, but
we do know a safe minimum.  If we encounter a packet that is larger than that
the minimum, we now send it via TCP instead to ensure it arrives.  We also
allow large packets that we cannot fragment or create ICMP replies for to be
sent via TCP.
