From 624d1164730d58a494cc5aa4afa37d02c41e83a7 Mon Sep 17 00:00:00 2001 From: Chris Leech Date: Tue, 23 May 2006 18:01:28 -0700 Subject: [I/OAT]: Make sk_eat_skb I/OAT aware. Add an extra argument to sk_eat_skb, and make it move early copied packets to the async_wait_queue instead of freeing them. Signed-off-by: Chris Leech Signed-off-by: David S.
