[U-Boot] e1000 Rx timeout with 82541ER

[André Schwarz]

Roy, Ben,

with latest e1000.c my 82541ER connected to a MPC5200 via PCI is no
longer working correctly - I get timeouts after few packets. After
having a quick look at the code changes it's obvious that I can't figure
out the problem quickly since there has been a lot of changes.

Using drivers/net/e1000.c from v2009.6 gives me back a working NIC, i.e.
the problem is likely to be there.

Have you tried some PCI cards after the PCIe changes ?

Any ideas ?
