inet: consolidate INET_TW_MATCH
TCP listener refactoring, part 2 : We can use a generic lookup, sockets being in whatever state, if we are sure all relevant fields are at the same place in all socket types (ESTABLISH, TIME_WAIT, SYN_RECV) This patch removes these macros : inet_addrpair, inet_addrpair, tw_addrpair, tw_portpair And adds : sk_portpair, sk_addrpair, sk_daddr, sk_rcv_saddr Then, INET_TW_MATCH() is really the same than INET_MATCH() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
