[INET]: Change protocol field in struct inet_protosw to u16
[acme@newtoy net-2.6.20]$ pahole /tmp/tcp_ipv6.o inet_protosw
/* /pub/scm/linux/kernel/git/acme/net-2.6.20/include/net/protocol.h:69 */
struct inet_protosw {
struct list_head list; /* 0 8 */
short unsigned int type; /* 8 2 */
/* XXX 2 bytes hole, try to pack */
int protocol; /* 12 4 */
struct proto * prot; /* 16 4 */
const struct proto_ops * ops; /* 20 4 */
int capability; /* 24 4 */
char no_check; /* 28 1 */
unsigned char flags; /* 29 1 */
}; /* size: 32, sum members: 28, holes: 1, sum holes: 2, padding: 2 */
So that we can kill that hole, protocol can only go all the way to 255 (RAW).
