Re: [PATCH net-next 3/3] net: Add table id from route lookup to route response

rt_fill_info which is called for 'route get' requests hardcodes the
table id as RT_TABLE_MAIN which is not correct when multiple tables
are used. Use the newly added table id in the rtable to send back
the correct table.

What RTM_GETROUTE returns is not the actual route but a description
of the routing decision which is why table id, scope, protocol, and
prefix length are hardcoded. This is indicated by the RTM_F_CLONED
flag. What you propose would break userspace ABI.
