mlxsw: spectrum_router: Add nexthop trap action support
Currently, nexthops are programmed with either forward or discard action
(for blackhole nexthops). Nexthops that do not have a valid MAC address
(neighbour) or router interface (RIF) are simply not written to the
adjacency table.
In resilient nexthop groups, the size of the group must remain fixed and
the kernel is in complete control of the layout of the adjacency table.
A nexthop without a valid MAC or RIF will therefore be written with a
trap action, to trigger neighbour resolution.
Allow such nexthops to be programmed to the adjacency table to enable
above mentioned use case.
