Subject: Re: 8168, PCI-Express, mac-version 0x3c000000, CFG_METHOD_4

Hi Francois Romieu,

I just tested out your patch for my r8168.
The card is a: r8168, PCI-Express, mac-version 0x3c000000 and the
realtek driver from the manufacutrer uses  CFG_METHOD_4 for it.
The card did NOT work with the current 2.6.23 kernel!

Your patch seems to work but  to strange behaviors still remain:

1) The dropped RX_packet count increases very very fast (see attached 
ifconfig.txt)
2) The card is reported as FIBRE by ethtool (see attached ethtool.txt)

I think (RTL_R8(PHYstatus) & TBI_Enable) should be false for this card. 
If I replace
this expression with "0" in thte code, then the card will be reported as 
Twisted Pair...
but I'am new to all this....

Also attached:
- modprobe r8168 debug=16
- dmesg
- eththool eth0
- lspci -vvx
- ifconfig eth0


greets Matthias
