Subject: Reset UTCP timers when learning a node's public key.
X-Git-Url: https://git.meshlink.io/?a=commitdiff_plain;h=88bd3d78991c721062506be7975f7564be4d82da;p=meshlink

Reset UTCP timers when learning a node's public key.

If we try to open a channel to a node whose public key we do not yet
have, a REQ_KEY request is sent out. When the answer comes back we know
the key, but we have to tell UTCP to reset the timers, otherwise we have
to wait for a retransmission timeout to occur before resending the SYN
packet.
