History
Richard Scheffenegger 8e0511652b Retain only mutually supported TCP options after simultaneous SYN 
When receiving a parallel SYN in SYN-SENT state, remove all the
options only we supported locally before sending the SYN,ACK.

This addresses a consistency issue on parallel opens.

Also, on such a parallel open, the stack could be coaxed into
running with timestamps enabled, even if administratively disabled.
