Subject: Handling receive packets with limited buffer space

In my modified ethoc.c driver, I am using only one receive buffer
descriptor due to limited space. This works fairly well for small
packets (arp, pings, etc.).

However, doing a 'wget' and downloading a file causes lots of drops and
thus results in a terminated connection.

How do I go about dealing with this? I tried stopping the queue
(netif_stop_queue) while I'm processing the rx skb and then resuming it
once I'm done, but this did not seem to help.

Any ideas on this?

Thanks for any help.
Amit
