   4 -- Currently we set two global tables
   5 -- prefix
   6 --    .family = The v4 or v6 family we are working in
   7 --    .route  = the A.B.C.D/X or Z:A:B::D/X string
   8 -- nexthop
   9 --    .metric = The metric we are going to use
  10 --    .ifindex = The outgoing interface
  11 --    .aspath = The aspath of the route
  12 --    .localpref = The localpref value

  14 -- Valid Return Codes:
  15 --   0 - Some sort of processing failure
  16 --       This turns into a implicit DENY
  17 --   1 - No match was found, turns into a DENY
  18 --   2 - Match found, turns into a PERMIT
  19 --   3 - Match found and data structures changed, turns into a PERMIT
  20 --       and a reread of the prefix and nexthop tables
