kernel config files (2.6.37.2 , 3.6.8, 3.7.8)

Hello.

I have a problem.

I have a motherboard with processor RDC8610. As PHY-chip used tlk100 (Texas
Instruments). tlk100 uses "Generic PHY-driver" from kernel.

When I compile a kernel 2.6.37.2 works fine.

When I compile a kernel 3.6.8 or 3.7.8 I have problems in the network.
The built-in network card (r6040) does not work pings.
ifconfig shows no errors, but the "RX bytes"> 0 while the "TX bytes" = 0! It
seems that the transmitter is not initialized or not working.

Rarely get messages on the console:

eth1: link UP
eth1: link DOWN

As I see it, the value "TX bytes" from ifconfig increased (but not
significantly)


Network cable is connected and not damaged.

I can see that from the kernel version 2.6.37.2 to 3.6.8, the NIC driver r6040
upgraded from 0.26 (30May2010) to 0.28 (07Oct2011).

I attach the configuration files of the kernel.

What is it? Bug in the new driver r6040?
Or am I doing wrong?
