From b0057c51db66c5f0f38059f242c57d61c4741d89 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 10 Oct 2010 19:55:52 +0000 Subject: [PATCH] tg3: restore rx_dropped accounting commit 511d22247be7 (tg3: 64 bit stats on all arches), overlooked the rx_dropped accounting. We use a full "struct rtnl_link_stats64" to hold rx_dropped value, but forgot to report it in tg3_get_stats64(). Use an "unsigned long" instead to shrink "struct tg3" by 176 bytes, and report this value to stats readers. Increment rx_dropped counter for oversized frames.
