Subject: [PATCH net-next 4/5] mlxsw: spectrum_router: Consolidate identical functions
From: Ido Schimmel <idosch@...lanox.com>
After the last patch mlxsw_sp_fib{4,6}_node_entry_link() and
mlxsw_sp_fib{4,6}_node_entry_unlink() are identical and can therefore be
consolidated into the same common function.
Perform the consolidation.
