Dear Wolfgang,

I am using mainline code (u-boot v2011.12) with 
P2020RDB-PC_SPIFLASH_config. Unfortunately it does not work as I thought, 
but fortunately we may have a solution (patch) to solve the problem.

Best regards,

Thomas Pohl

Yes, this is supposed to work.  We've even seen running TFTP and
Netconsole over Ethernet over USB...

Hm... you are not running mainline code, right?  Because we always
have a single network interface active at any time.

I recommend you undo any modifications made to the network stack,
and/or try plain mainline code instead.
