Subject: net/mvpp2: remove debug log on fast-path
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fa876f3ae29885321c752468c22ad1c06a7a498c;p=dpdk.git

net/mvpp2: remove debug log on fast-path

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: acab7d58c81b ("net/mvpp2: convert to dynamic logging")
