Hi,

I know A0 versions of the AST2600 had an issue where eth0 was not 
working, but the errata indicates this is fixed in later revisions.

I am seeing an issue on the EVB board though where eth0 (MAC1) is not 
functional. The other three ports all function as expected.

On my DHCP host machine I can see DHCP requests from the AST2600, and 
replies are sent. Looking at /proc/interrupts it looks very much like no 
IRQs are ever generated for incoming packets.

Thanks

Graeme
