From d142e1ac10893b7a5b0240809325ac737237a57a Mon Sep 17 00:00:00 2001 From: Nelson Escobar Date: Wed, 13 Jul 2016 09:52:34 -0700 Subject: [PATCH] net/enic: fix calculation of truncated packets The calculation of truncated packets didn't take into account packet errors due to the adapter not having buffers, causing both the ipackets, and imissed counts to be wrong if such errors occurred. In order to properly calculate the number of packets truncated, we need to subtract the count of errors due to no buffers.
