Subject: Handling receive packets with limited buffer space
Date: Fri, 19 Mar 2010 02:41:18 -0700 [thread overview]
Message-ID: <20100319094118.GA30249@debian> (raw)
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
