Since the SACK receive cache doesn't need the data to be in host
order we also remove the ntohl in the checking loop.

 ...

-	for (i = 0; i< num_sacks; i++) {
-		__u32 start_seq = ntohl(sp[i].start_seq);
-		__u32 end_seq =	 ntohl(sp[i].end_seq);
+	for (i = 0; i < num_sacks; i++) {
+		__u32 start_seq = sp[i].start_seq;
+		__u32 end_seq = sp[i].end_seq;

 ...

 		}
 		tp->recv_sack_cache[i].start_seq = start_seq;
 		tp->recv_sack_cache[i].end_seq = end_seq;

Ok, and now the sack cache and the real sack blocks are
stored in net-endian and this works out because we only
make direct equality comparisons with the recv_sack_cache[]
entry values?
