Subject: [dpdk-dev] [PATCH v2] fm10k: add debug info for actual Rx/Tx func
Date: Fri, 27 Nov 2015 09:54:12 +0800	[thread overview]
Message-ID: <1448589252-16195-1-git-send-email-jing.d.chen@intel.com> (raw)
In-Reply-To: <1448344809-10054-1-git-send-email-jing.d.chen@intel.com>

From: "Chen Jing D(Mark)" <jing.d.chen@intel.com>

After introducing vPMD feature, fm10k driver will select best
Rx/Tx in running time. Original implementation selects Rx/Tx
silently without notifications.

This patch adds debug info to notify user what actual Rx/Tx
func are used.
