CLLF860T FEC problem in linux-2.4.0-test4-pre6

[Graham Stoney]

Hi dudes,

I've just had a shot at running the latest 2.2.4-test4-pre6 snapshot on a
CLLF860T board, and I'm finding that opening the FEC driver fails, because
the PHY hasn't been recognised.  Firstly though, I had to apply this patch
to get the FEC initialised:

diff -ur linux-2.4.0-test4-pre6/drivers/net/setup.c linux-2.4.0-test4-pre6.cllf/drivers/net/setup.c

I have CONFIG_FEC_QS6612 enabled in fec.c, but it appears that I'm never
getting an MII interrupt, because fec_enet_interrupt is never called.
Hence, neither mii_discover_phy function gets called, and fec_enet_open later
fails with -ENODEV.

Has anyone got any clues on this before I dive into it tomorrow?

Thanks,
Graham
