[mpls-linux-general] regarding tranport Layer port....

[<vvk...@hs...>]

Hi  Experts !

     I  want to clarify my doubt, whether  IP uses some encoding
technique...............while tranmitting the
packet........

Assume sk_buff  pointer   "skb"    , i am trying to get the port number of the
application from the TCP header in the following way.........

skb->h.th->dest  ........./* Destination port ........*/

We are trying to transfer  certain traffic based on Transport layer port, as
part of the application of
Traffic Engineering .......

For telnet application : port : 23 ,   but when i get the dest value in
"mpls_output2" function in  "mpls_output.c" file
it is showing some other values like : 319, 510 ................   As everybody
knows Telnet port : 23

I tried to print it normally  and then   __const_htons,  __const_htons
..............

i didn't get the dest port : 23 in any of  the cases..........

Please guide me in this ..............

Thanks in advance........
Regards,Ramki kvv.
