[dpdk-dev] [PATCH v2] fm10k: add debug info for actual Rx/Tx func

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" 

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.
