This is a note to let you know that I've just added the patch titled net/mlx5e: Count GSO packets correctly to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-mlx5e-count-gso-packets-correctly.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Mon Mar 27 18:17:54 CEST 2017 From: Gal Pressman <galp@xxxxxxxxxxxx> Date: Tue, 21 Mar 2017 15:59:18 +0200 Subject: net/mlx5e: Count GSO packets correctly From: Gal Pressman <galp@xxxxxxxxxxxx> [ Upstream commit d3a4e4da54c7adb420d5f48e89be913b14bdeff1 ] TX packets statistics ('tx_packets' counter) used to count GSO packets as one, even though it contains multiple segments. This patch will increment the counter by the number of segments, and align the driver with the behavior of other drivers in the stack. Note that no information is lost in this patch due to 'tx_tso_packets' counter existence. Before, ethtool showed: $ ethtool -S ens6 | egrep "tx_packets|tx_tso_packets" tx_packets: 61340 tx_tso_packets: 60954 tx_packets_phy: 2451115 Now, we will see the more logical statistics: $ ethtool -S ens6 | egrep "tx_packets|tx_tso_packets" tx_packets: 2451115 tx_tso_packets: 60954 tx_packets_phy: 2451115 Fixes: e586b3b0baee ("net/mlx5: Ethernet Datapath files") Signed-off-by: Gal Pressman <galp@xxxxxxxxxxxx> Cc: kernel-team@xxxxxx Signed-off-by: Saeed Mahameed <saeedm@xxxxxxxxxxxx> Acked-by: Alexei Starovoitov <ast@xxxxxxxxxx> Signed-off-by: David S.
