From e470757d6179eb8998881ac2706927d4d0cb0e54 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 27 Aug 2009 13:55:13 +0000 Subject: pktgen: use netdev_alloc_skb netdev_alloc_skb is NUMA node aware. Also, don't exhaust atomic emergency pool. Don't want pktgen to cause OOM behaviour. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
