Thank you!  It took a few tries, but I now have the SC-SATG11's
RealTek 8169S talking.  The SC-SATG11 needs rgephy which 2.0.2 didn't
have, but I was in the process up updating to 3.0.1 anyway.

Although it doesn't come up properly every time.  A couple of times
I got:

re0 at pci1 dev 0 function 0: RealTek 8169S Single-chip Gigabit Ethernet
re0: interrupting at eb164 irq 1
re0: using 512 tx descriptors
rgephy0 at re0 phy 7: RTL8169S/8110S 1000BASE-T media interface, rev. 0
rgephy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto
re0: diagnostic failed, failed to receive packet in loopback mode
re0: attach aborted due to hardware diag failure
rgephy0 detached

Both times a reboot fixed it.
