FYI: I spotted a small bug just looking at this patch. The code that
writes to the PHY registers has a typo in it:
> - unsigned csr = TULIP_CSR_READ(sc, csr_srom_mii) & (MII_RD|MII_DOUT|MII_CLK);
> + unsigned csr;
> +

> + (devaddr << 23) | (regno << 18) | data);

That 0x8000000 up there should be 0x80000000. The 'busy' bit is bit 31.
Also, LinkSys sells a 10/100 card that uses the PNIC chip.
