Modified Files:
        src/sys/dev/pci: if_msk.c if_mskvar.h

Log Message:
sync OpenBSD if_msk.c revs 1.66-1.79 skipping framework changes and already
present changes:
- Make Yukon-2 FE+ (88E8040, 88E8042) work
- 88E8057 is a Yukon 2 Ultra 2, and this might make it work on a little
  shiny green box in Japan
- Prevent null pointer dereference that could happen when we process an RX
  interrupt that was queued while stopping the interface.
- Remove holdover XMAC II writes/reads inherited from sk as
  they aren't required and cause problems like the 88E8072
  hard locking a system when enabling macsec bypass.
- Bypass macsec on extreme/supreme based chips.
  Makes my 88E8072 work.
- Add detach support to a few more drivers, and in others do the neccessary
  operations in the detach function in the right order.

towards resolution of PR kern/53301 but will need more work

tested by John Halfpenny on another 8040/Yukon-2 FE+ and reported
improving behaviour (system hang to stall) so committing as stopgap; also
tested on my SK-9E22 (Yukon-2 XL), there works without any issues both before
and after
