Subject: [dpdk-dev] [PATCH] net/i40e: exclude internal packet's byte count
Date: Wed, 31 May 2017 18:53:27 -0400	[thread overview]
Message-ID: <1496271207-36688-1-git-send-email-qi.z.zhang@intel.com> (raw)

Tx/Rx byte counts of internal managed packet should be
exluded from the total rx/tx bytes.

Fixes: 9aace75fc82e ("i40e: fix statistics")
Cc: stable@dpdk.org
