Subject: net: rate-limit warn-bad-offload splats.
From: Ben Greear <[email protected]>
[ Upstream commit c846ad9b880ece01bb4d8d07ba917734edf0324f ]
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.
