3.6.11.3 stable review patch. If anyone has any objections, please let me know.
------------------ 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. Signed-off-by: Ben Greear <[email protected]> Signed-off-by: David S.
