From c846ad9b880ece01bb4d8d07ba917734edf0324f Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Fri, 19 Apr 2013 10:45:52 +0000 Subject: [PATCH] net: rate-limit warn-bad-offload splats. If one does do something unfortunate and allow a bad offload bug into the kernel, this the skb_warn_bad_offload can effectively live-lock the system, filling the logs with the same error over and over. Add rate limitation to this so that box remains otherwise functional in this case. Signed-off-by: Ben Greear Signed-off-by: David S.
