From 275757e6bae15a8621130907a78096afd1e15d2c Mon Sep 17 00:00:00 2001 From: Gustavo A. R. Silva Date: Mon, 16 Oct 2017 16:36:52 -0500 Subject: ipv6: 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. Signed-off-by: Gustavo A. R. Silva Signed-off-by: David S.
