[src/trunk]: src/sys/dev/pci sync and adapt with OpenBSD if_msk.c rev. 1.43-1...
details: https://anonhg.NetBSD.org/src/rev/9b7f49280674
branches: trunk
changeset: 323388:9b7f49280674

description:
sync and adapt with OpenBSD if_msk.c rev. 1.43-1.65 (modulo some
cosmetics, stuff we already had, or stuff which does not apply due
to different frameworks):
- Add support for fiber on 88E8021/22
- Avoid unnecessary resets. This should make fiber 88E8021/22 work completely
- Only probe phy's at address 0; gets rid of bogus phy's on the
Marvell Yukon 88E8036
- Remove an unused function msk_setfilt() which was copied from sk(4)
- Make msk(4) detachable
- Simplify the combination use of pci_mapreg_type()/pci_mapreg_map()
