Subject: [patch net-next 12/19] mlxsw: core: Change emad trap group settings
From: Nogah Frankel <nogahf@...lanox.com>
Currently, the emad trap init was done in the core. In the future we will
want to add some changes to the traps groups, according to device type.
This commit create a driver function to create the trap group for the
emad, so later it can be changed by devices. It also changes the emad
registration to use the new generic functions.
