Well, since I was the last person to rewrite the options code in
Linux(*), you might as well tell me here :)

I'm not sure exactly what the issue is here. There isn't excessive
padding: 99.9% of packets have only a timestamp option and thus have
the minimal amount of padding. The advantage of writing/reading
aligned data outweighs better compaction in SYN frames since there's
(currently) no options that we excluded because of the padding.

(*) it should be in .27, maybe .28
