Date: Fri, 19 Apr 2013 13:45:52 -0700 From: greearb@...delatech.com To: netdev@...r.kernel.org Cc: Ben Greear <greearb@...delatech.com> Subject: [PATCH] net: rate-limit warn-bad-offload splats. From: Ben Greear <greearb@...delatech.com> 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.
