[realtek] interrupts error on ppc

[leeyang]

hi!

I am trying to use rtl8139 NIC on Motorola
Sandpoint evaluation board for MPC8245.
But here are some problems I think related
with interrupts.

I put some my console msg below:

......

the numbers of interrupts (55) goes up but the bad number unchanged
as time fly by.

Could you explain the pop msg here and Why the card can not
successfully work.
BTW,I knew there are different between 8139too and rtl8139 driver,
but I can not compile rtl8139.c in my cross compile enviroment.

Best regards.
