netfilter: Fix switch statement warnings with recent gcc.
More recent GCC warns about two kinds of switch statement uses: 1) Switching on an enumeration, but not having an explicit case statement for all members of the enumeration. To show the compiler this is intentional, we simply add a default case with nothing more than a break statement. 2) Switching on a boolean value. I think this warning is dumb but nevertheless you get it wholesale with -Wswitch. This patch cures all such warnings in netfilter. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Pablo Neira Ayuso <pablo@netfilter.org>
