Ethernet Driver and NAPI

Postby milanjoshi » Thu Nov 21, 2013 5:27 pm

Hi all,

I have at91rm9200 based board with linux kernel 2.6.30.
When I do flood on ethernet, kernel spends all time serving soft irqs because of which
application fails to kick watchdog timer and board restarts. :shock:

/drivers/net/arm/at91_ether.c is the driver used for ethernet.

Any idea regarding this?
