hello all,

i was trying to simulate a tcp socket server on userspace.. and i came
across this problem.. 

I am construction an ip packet with tcp..It goes like this..

packet.tcp.sadd=<address>
packet.tcp.dadd=<address>
packet.tcp.source=<sourceport>
..
..
..

I had to timestamp the tcp packets and i didnt know how to set 
the tcp options..if i dont timestamp a normal tcp client doesnot
recognise my packet...I dont understand the timestamp clock and 
tsval stuff .. and also how do i set the tcp options.. there are no
specific fields in tcp header structure !

thanks in advance,

best regards
srinath
