After a couple days of messing around with the sam7x port I have found
some more problems.
1-the emac driver needs :
isr = inr(EMAC_ISR);
right after enabling the irq, otherwise we never see interrupts if you
have packets come in before the irq is enabled.
2-There is a serious packet loss problem, I'm trying to run some data
streaming and something is very wrong the EMAC_FRO (frames ok
)register matches what I am expecting but my application see's about
1/10 of the packets.

Revision 1.1 2006/08/31 18:58:47 haraldkipp
* This had been tested on the SAM9260, but loses Ethernet packets
* for a yet unknown reason.
Looking at the code I can't see anything really wrong with it but some
parts look strange and I'd be be happy to work with Harald or anyone
else to try and clear things up.
