From a5de43c1e292b26d2784162871515973d514b635 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Thu, 5 Sep 2013 21:44:00 +0300 Subject: staging: octeon-ethernet: remove skb alloc failure warnings Remove skb allocation failure warnings. They will trigger a page allocation warning already. Also, one of the warnings was not ratelimited, causing the box to lock up under heavy traffic & low memory.
