mge, mii/e1000phy

Hi,

I've been trying to get CURRENT running on a TS-7800 [1].
It's based around a Marvell Orion SoC, with a Marvell 88E1118 PHY.

It boots and tries to do bootpc_init. This fails because there are no
packets coming in or going out. 

A few thing's I've noticed:
 - The PHY is misdetected as an 88E1116. Changing sys/dev/mii/miidevs so
   it's detected as the 88E1118 it really is doesn't help.
 - sys/dev/mii/e1000phy.c appears to contain a bug:
   e1000phy_reset performs a switch on MII_MODEL(esc->mii_model) while
   the rest of the code just uses esc->mii_model. This seems to be wrong
   as the cases for 1118 (or 1116) are not triggered. Changing this also
   doesn't appear to help.
 - Forcing the mge driver to IFM_100_TX (in mge_set_port_serial_control)
   does work. The system manages to acquire a DHCP address. 
 - CURRENT does work correctly on my Sheevaplug, which has a Marvell
   88E1116R PHY (at least, it's identified as one, I've not checked any
   further).

Does anyone have any ideas on what might be causing this or what to try next?
