To re-iterate the question, should I also post a patch for changing
rte_lpm_lookup() to add "const" to "struct rte_lpm *lpm" argument?
rte_lpm_lookup_bulk_func() and rte_lpm_lookupx4() already take lpm as
const.
I'm pushing because otherwise I get a const discard warning in the
scalar version of rte_lpm_lookupx4() utilizing rte_lpm_lookup().
