Subject: [Intel-wired-lan] [PATCH RESEND][next] igb: Fix fall-through warnings for Clang
Date: Fri, 5 Mar 2021 03:05:11 -0600	[thread overview]
Message-ID: <20210305090511.GA139181@embeddedor> (raw)

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