Re: kern/58508: experimental wg(4) queues LIFO, not FIFO, pending first handshake

[Taylor R Campbell <riastradh%NetBSD.org@localhost>]

On reflection, I realize that LIFO and FIFO are not the right terms
here.

A single-entry queue is always both LIFO (last-in/first-out) and
FIFO (first-in/first-out).

What changed is the choice of which packets to drop when we are asked
to transmit new ones and the (single-entry) queue has filled up.  Do
we drop the oldest packet, or the newest packet (or something else)?

Previously I had chosen drop-newest (but not for any particular reason
I can remember, and certainly not for any reason I wrote down).  Now
the choice is drop-oldest, like arp/ndp does.

Too late to fix the commit message, oh well.
