From 256ff05a9cae7484e2197cde4401dfa1f21d5a6f Mon Sep 17 00:00:00 2001 From: Harry van Haaren Date: Wed, 4 Nov 2015 16:14:43 +0000 Subject: [PATCH] ixgbe: fix Rx errors statistics for UDP checksum This patch removes l3_l4_xsum_errors from rx errors. The reason to remove it is that UDP packets have an optional checksum, and when not calculated the checksum field should be set to zero. When the checksum is not calculated (zero-ed out), the hardware still counts a valid UDP packet as an l3_l4_xsum_error. This hardware issue is documented in 82599 errata, titled: "Integrity Error Reported for IPv4/UDP Packets with Zero Checksum" The solution is to remove l3_l4_xsum_errors from rx_errors, as discussed on http://thread.gmane.org/gmane.comp.networking.dpdk.devel/25590/ Fixes: f6bf669b9900 ("ixgbe: account more Rx errors") Suggested-by: Martin Weiser Signed-off-by: Harry van Haaren --- drivers/net/ixgbe/ixgbe_ethdev.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/net/ixgbe/ixgbe_ethdev.c b/drivers/net/ixgbe/ixgbe_ethdev.c index c0dbf79f1a..0b0bbcfcac 100644 --- a/drivers/net/ixgbe/ixgbe_ethdev.c +++ b/drivers/net/ixgbe/ixgbe_ethdev.c @@ -2492,7 +2492,6 @@ ixgbe_dev_stats_get(struct rte_eth_dev *dev, struct rte_eth_stats *stats) total_missed_rx + hw_stats->illerrc + hw_stats->errbc + - hw_stats->xec + hw_stats->rfc + hw_stats->fccrc + hw_stats->fclast; -- 2.20.1
