Subject: [patch net-next 04/19] mlxsw: spectrum: Use generic listener struct for rx traps
From: Nogah Frankel <nogahf@...lanox.com>
Replace the old rx listener struct definitions by the generic ones.
Use the new generic registering / unregistering functions for them.
Add some macros to organize the trap list.
