hi,

i have problems with the FEC on a i.MX25 3-Stack board. the kernel is
v2.6.34-rc2 plus the following patch:
http://patchwork.ozlabs.org/patch/41235/

the following traces are generated at boot time:

FEC Ethernet Driver
fec: PHY @ 0x1, ID 0x20005ce1 -- unknown PHY!
...
eth0: config: auto-negotiation on, 100FDX, 100HDX, 10FDX, 10HDX.
...
FEC ENET: rcv is not +last
FEC ENET: rcv is not +last
FEC ENET: rcv is not +last
FEC ENET: rcv is not +last
...

the PHY of the board is a DP83840, which is not supported by the
driver. could this be the problem? i tried to make the kernel think
the DP83840 is a DP83848, which is supported, but the behaviour is the
same except the 'unknown PHY' warning.

any idea what could be wrong?
