Hi,
There are differences in the MACTYPE register between the 88X3310
and 88X3340. For example, the 88X3340 has no support for XAUI.
This is documented in the data sheet, and in the definitions of
these values - note that MV_V2_3310_PORT_CTRL_MACTYPE_XAUI and
MV_V2_3310_PORT_CTRL_MACTYPE_XAUI_RATE_MATCH are only applicable
to the 88X3310 (they don't use MV_V2_33X0_*).
