  Modified files:
    sys/dev/cxgb         cxgb_l2t.c 
    sys/netinet          if_ether.c if_ether.h 
  Log:
  Don't duplicate the whole of arpresolve to arpresolve 2 for the sake
  of two compares against 0. The negative effect of cache flushing
  is probably more than the gain by not doing the two compares (the
  value is almost certainly in register or at worst, cache).
  Note that the uses of m_freem() are in error cases and m_freem()
  handles NULL anyhow. So fast-path really isn't changed much at all.
