[NETFILTER]: nf_conntrack_{tcp,sctp}: shrink state table
The TCP and SCTP conntrack state transition tables only holds small numbers, but gcc uses 4 byte per entry for the enum. Switching to an u8 reduces the size from 480 to 120 bytes for TCP and from 576 to 144 bytes for SCTP. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
