Subject: POI: nvidia forcedeth phy id not present


 guess this is not a real bug report, just some POI:

1. one-liner: the realtek 8211cl driver (PHY 0x732) is not present in the forcedeth.c driver

2. full description: my mainboard (Asus M4N82 deluxe) has an onboard nvidia/realtek 8211cl
ethernet card.
The forcedeth detects the card, but is unable to bring up the phy, disabling additional features
(MTU limited to 1500).
The card identifies itself as 'PHY OUI 0x732', which is not even present in the forcedeth driver.
I feel not yet capable of developing a patch for this, I'm right now learning about linux driver
structure

4. kernel version: Linux version 3.2.23 ( root@...egtuig) (gcc version 4.6.3 (Gentoo 4.6.3 p1.3,

The point of improvement is not disabling the driver itself. but it would unlock some features
highly appreciated.
If required, I'll develop some patch for this, but it may take some time before I guess I know
how the chip detection actually works.

kind regards,
