  From: Liron Himi <lironh@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")
