sgsnemu: no outgoing GTP-U in "createif" mode

[Viktor Tsymbalyuk]

Hello,

I tried to run sgsnemu in "createif" mode - transfer traffic via tun 
interface.
tun interface created and routing too. But there are no outgoing GTP-U 
from test machine. (in my scenario sgsnemu on separated server).
 From gdb it looks, that in cb_tun_ind function ipm->pdp is 0x0, as result
gtp_data_req(gsn, ipm->pdp, pack, len);
not running.
After changes like below, it's start working. Does I correctly 
understood internal logic?

-       ipset((struct iphash_t *)pdp->peer, &addr);
+       ipset(iph, &addr);

         state = 2;              /* Connected */


If need more test details, please let me know.
