Subject: net/e1000/base: fall through explicitly
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=df01c0ee277d51f81d7d72501dba97550d3b6c4a;p=dpdk.git

net/e1000/base: fall through explicitly

Found some inconsistent code comments when it came to when we "fall
through", so made them more consistent and non-repetitive.

This patch adds/changes fall through comments to address new warnings
produced by gcc 7.
