I think that's where I started on this. I didn't change sockaddr_ll and
it didn't work for IPoIB link level messages but at this point, I'm no
longer 100% sure so I will check again (it may have been due to some
other problem).

If sockaddr_ll struct is left alone, I think it may be a problem on the
receive side where the size of that struct is used.
