Network interrupts

Hi All,

I am a newbie trying to bring up a board on MontaVista Linux. The board has an Intel IOP321 processor with an ARM core. The network interface is an Intel 82544EI. I have got as far as registering an ISR for the ethernet and entering the ISR. The logs seem to suggest that the interface was configured correctly. Following the config, the kernel is trying to connect to an NFS server (for the rootfs) but tcpdump on the server shows not a single packet from this interface. I am printing the ICR (interrupt cause read) register inside the handler and below is the output I see: ============================================================= Intel(R) PRO/1000 Network Driver - version 5.0.43 Copyright (c) 1999-2003 Intel Corporation.

Is there anything else I need to do before I can see some packets on the wire? Any help or pointers would be really appreciated.

TIA, Guru

I've got a similar problem with the nfs boot. Can anybody give me a hint how to solve this problem. Thanks in advance Bernhard
