Subject: [PATCH][next] net: axienet: Fix fall-through warning for Clang

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Fri, 28 May 2021 14:58:31 -0500

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding a fallthrough statement instead of just
letting the code fall through to the next case.

JFYI: We had thousands of these sorts of warnings and now we are down
      to just 25 in linux-next. This is one of those last remaining
      warnings.
