The patch installed and is working correctly on a generic (i386,MP) 5.0
distribution.

This is not quite what FreeBSD has:
If you look at msk_phy_power it is not just for EC_U but rather:
== SK_YUKON_EC_U ||
== SK_YUKON_EX ||
= SK_YUKON_FE_P
(linux has this as the SKY2_HW_ADV_POWER_CTL flag)
additionally,
OURREG5 keeps PCI_CTL_TIM_VMAIN_AV_MSK bits, not written 0
setting OURREG1 to 0 missing
B2_GP_IO workaround for yukon-ultra/extreme missing
Mea Culpa, Jonathan is right because I actually took my patch from
NetBSD (if_skreg.h 1.13 and if_msk.c 1.22). I'm sorry for the
hassle.
So here is the diff with the changes I suggested, can you verify
this works for you as well?
