   Please see my previous clarification email on the what and the why
   about the "route.h.diff" patch.  

   I spent some time looking into the issue and found the problem 
   is the if_tap interface turns out to be one of those interfaces 
   that claims to be of IFT_ETHER type, but does not touch the 
   "if_link_state" variable.

   Please try the new patch at

     http://people.freebsd.org/~qingli/ecmp-tap.diff

   Let me know how it works out for you.

P.S.  You really just need the 2-line fix in the if_tap.c file.
      route.h is slightly touch to be (ifp) instead of just ifp in
      the macro.
