From ad04378cecca9c33b5ea3e46aa4ed71b15e0be0c Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Tue, 18 Oct 2011 01:50:56 +0000 Subject: [PATCH] mlx4_en: Checksum counters per ring Not updating common counters from data path. The checksum counters are per ring, summarizing them when collecting statistics. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.
