Subject: Immediately exchange keys when establishing a meta connection.
X-Git-Tag: release-1.0.12~4
X-Git-Url: https://www.tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=ed14ef93b47622ba13099dfc6be5335222e987a6

Immediately exchange keys when establishing a meta connection.

This in turn will trigger PMTU discovery, and ensures nodes know each others
reflexive UDP address and port.
