[eepro100] onboard NIC switching from Suspended to Active

[Tru Huynh]

Hello,

Background: mobo Rocky 3732 dual cpu board with only 1 cpu
PIII-800EB and uniprocessor kernel (redhat 7.1) with the
eepro100(1.09j-t).

when running bonnie++ from an other machine accessing a nfs
exported filesystem, the NIC status switches from Active to Suspended
for a during a few minutes then is stuck in Suspended mode.

Any idea?

Best regards,

Tru
