[IPV4]: align inet_protos[] on SMP
As IPPROTO_TCP is 6, it makes sense to make sure inet_protos[] array is properly cache line aligned to avoid false sharing on SMP. c0680540 b peer_total c0680544 b inet_peer_unused_head c0680560 B inet_protos On i386 this example, we can see that inet_protos[IPPROTO_TCP] shares a potentially hot (and modified) cache line.
