It tells us that packet comes from remote address that
we can reach directly, without using gateway. The most
common values for nh_scope are RT_SCOPE_LINK (when nh_gw is
unicast address), RT_SCOPE_HOST (when nh_gw is not set or
is local address) and RT_SCOPE_NOWHERE (when we have a
local route). You can check fib_check_nh() and
fib_create_info() for reference.
