sk(4) patch

[Michal Belczyk]

Hello,

here (*) is a patch for sk(4) which is basically made of:

1) a fix taken from OpenBSD that made my onboard NIC work with jumbo
frames enabled
(http://sources.zabbadoz.net/freebsd/patchset/EXPERIMENTAL/if_sk.c-yukon-jumbo-frames.diff)
2) a fix for detecting correctly on-chip RAM size
(http://sources.zabbadoz.net/freebsd/patchset/EXPERIMENTAL/if_sk_88E8001-ram.diff)
3) a feature for printing more VPD data for debugging
4) style cleanups reducing (a bit) diff between DragonFly and FreeBSD (HEAD)
5) replace of [xg]mac_calchash() with sk_[xg]mchash() which use
ether_crc32_[lg]e() instead of rolling own crc calculation functions
6) all other changes i've forgotten to write above :D

Part of dmesg, the board is ASUS A7V880:
skc0: <Marvell Gigabit Ethernet> port 0xe400-0xe4ff mem 0xfe800000-0xfe803fff

The box is connected via crossover cable to freebsd-stable with em(4)
inside, jumbo frames are enabled, NFS is still working ;-)

Could anyone take a look at it, please?
