Log Message:
wg(4): Queue pending packet in FIFO order, not LIFO order.
Sometimes the session takes a seconds to establish, for whatever
reason. It is better if the pending packet, which we queue up to
send as soon as we get the responder's handshake response, is the
most recent packet, rather than the first packet.
That way, we don't wind up with a weird multi-second-delayed ping,
followed by a bunch of dropped, followed by normal ping timings, or
wind up sending the first TCP SYN instead of the most recent, or what
have you. Senders need to be prepared to retransmit anyway if
packets are dropped.

first handshake
