From fcfd6dfab97006d44c7db5d6c908eac383af6649 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 16 Oct 2017 15:48:55 -0500 Subject: ipv4: mark expected switch fall-throughs In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in some cases I placed the "fall through" comment on its own line, which is what GCC is expecting to find. Addresses-Coverity-ID: 115108 Signed-off-by: Gustavo A. R.
