2.4.0-test11 - MPC860T FEC question.

[Wolfgang Denk]

Dan,

I just found another problem with the FEC / MII code. It happens when
I try to use BOOTP in the LInux kernel (I haven't been doing this for
a long time, since _if_ we use BOOTP, we do so in PPCBoot,  and  pass
all information to the kernel instead of running BOOTP twice).

Here is what I see:

It seems the "link up" interrupt comes much too late for the
"IP-Config" part; shouldn't we wait in fec_enet_open() for
"fep->link" to come up?

And do you have an idea why there is a "eth1" detected?
