Module Name:    src
Committed By:   riastradh
Date:           Mon Sep  7 01:14:42 UTC 2020

Modified Files:
        src/sys/net: if_wg.c

Log Message:
wg: Use a global pktqueue rather than a per-peer pcq.

- Improves scalability -- won't hit limit on softints no matter how
  many peers there are.
- Improves parallelism -- softint was kernel-locked to serialize
  access to the pcq.
- Requires per-peer queue on handshake init to avoid dropping first
  packet.
  . Per-peer queue is currently a single packet -- should serve well
    enough for pings, dns queries, tcp connections, &c.
