From: Sven Schnelle <sv...@stackframe.org>
Netbsd isn't able to detect a link on the emulated tulip card. That's
because netbsd reads the Chip Status Register of the Phy (address
0x14). The default phy data in the qemu tulip driver is all zero,
which means no link is established and autonegotation isn't complete.
Therefore set the register to 0x3b40, which means:
Link is up, Autonegotation complete, Full Duplex, 100MBit/s Link
speed.
Also clear the mask because this register is read only.
