The ASIC on the 3c905C appears to be manufactured by Broadcom (previous
ones were made by Lucent). The Broadcom chip also appears to use an
internal PHY made by Broadcom which uses the Broadcom OUI. This is different
from previous ASICs which always returned 0 in the PHY ID registers.
To account for this, I added the necessary ID values for the Broadcom
PHY so that it can be detected and attached using the 3Com PHY driver
instead of defaulting to the generic one.
