Subject: Re: [PATCH v5 7/7] TCPCT part 2g: parse cookie pair and 64-bit timestamp

Parse cookie pair extended option (previously defined).

Define and parse 64-bit timestamp extended option (and minor cleanup).
However, only 32-bits are used at this time (permitted by specification).

Every bit is sacred.  Use as few bits as possible in the tcp_sock
structure, at the expense of performance.

[v5 fixed trivial error]

Requires:
   net: tcp_header_len_th and tcp_option_len_th
   TCPCT part 2f: cleanup tcp_parse_options
