Subject: [dpdk-dev] [PATCH v1 02/38] net/mvpp2: remove debug log on fast-path

From: Liron Himi <lironh at marvell.com>

in case of non-ip frame the current code reached the 'default'
case which result with function call to log a msg.
those kind of calls should not be performed on fast-path.

The performance for this kind of frames increased by 50%

Fixes: acab7d58c ("net/mvpp2: convert to dynamic logging")
