[Click] tcp->thdport and udp->uh_dport not returning correct values

[milos rovcanin]

Greetings,

Like it's said in the subject, this code:

click_ether * eth = (click_ether *)p->data();
click_ip6 * ip6 = (click_ip6 *)(eth+1);

 if(ip6->ip6_nxt == 6) {
   click_tcp* tcp = (click_tcp*)(ip6+1);
   src_port = tcp->th_sport;
   dst_port = tcp->th_dport;
}

just won't return correct values for dst_port and src_port! I have checked
it in Wireshark too.
What am I doing wrong?

Thanks in advance!
