Subject: [PATCH RESEND][next] net/packet: Fix fall-through warnings for Clang
Date: Fri, 5 Mar 2021 03:44:29 -0600 [thread overview]
Message-ID: <20210305094429.GA140795@embeddedor> (raw)
In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break statement instead of letting the code fall
through to the next case.
