Re: [ECOS] ecos net stack query

Hi:

I have just modified the ping_lo_test.c application to ping an external
address instead of the loopback address. I run only this application.
My board is sending out a gratituous ARP on startup and when the application
opens a RAW socket and sends an ICMP echo req, the stck sends
an ARP request. It gets back an ARP reply that gets queued up in the
arpintrq and seems to never get processed. it remains in the queue.

I net isr for ARP , is never getting called. I think register_netisr()
itself is not getting called.

The cyg_net_init() call that handles isr's is not getting a chance to run..

thanks,
/Badri
