Are you using the latest code in Git, or the 1.5.1 code on linuxwimax.org?  I 
believe this is already fixed in Git, but didn't make it into 1.5.1.

There are actually a whole pile of structure alignment issues in 1.5.1, so I 
would strongly recommend pulling the wimax network service code from Git before 
continuing.
