tcp: Document use of undefined variable.
Both tcp_timewait_state_process and tcp_check_req use the same basic
construct of
struct tcp_options received tmp_opt;
tmp_opt.saw_tstamp = 0;
then call
tcp_parse_options
However if they are fed a frame containing a TCP_SACK then tbe code
behaviour is undefined because opt_rx->sack_ok is undefined data.
This ought to be documented if it is intentional.
