RTL8111C not working consistently in -current

[Brad du Plessis <bradd%cat.co.za@localhost>]

Hi all,

I've got a DFI motherboard with an RTL8111C onboard NIC. Relevant dmesg:

*snip*
> re0 at pci2 dev 0 function 0: RealTek 8168B/8111B PCIe Gigabit 
> Ethernet (rev. 0x02)
> re0: interrupting at ioapic0 pin 17
> re0: Ethernet address 00:01:29:2b:1c:5a
> re0: using 256 tx descriptors
> rgephy0 at re0 phy 7: RTL8169S/8110S/8211 1000BASE-T media interface, 
> rev. 2
> rgephy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
> 1000baseT-FDX, auto
*snip*

I put a log into the re_attach in rtl8169.c and its read the sc_rev=24.

My problem is that the device operates erratically and will sometimes 
work 100% after a reboot. Most of the time though I see lots of these 
when it doesn't work:

*snip*
> /netbsd: re0: reset never completed!
> /netbsd: re0: PHY write reg 0 <- 8400 failed
> /netbsd: re0: PHY write reg 1f <- 1 failed
> /netbsd: re0: PHY write reg 9 <- 273a failed
> /netbsd: re0: PHY write reg e <- 7bfb failed
> /netbsd: re0: PHY write reg 1b <- 841e failed
> /netbsd: re0: PHY write reg 1f <- 2 failed
> /netbsd: re0: PHY write reg 1 <- 90d0 failed
...

I contacted DFI directly and they have told me that the exact chipset is 
RTL8111C-VC-GR (if that means anything). I've tried it on netbsd-4 too 
and although I get a "revision unknown" message at startup the device 
does exactly the same thing (i.e. sometimes following a reboot it will 
work, reboot again and it won't).

Any help would be appreciated.

Thanks,
Brad
