This patch series extends lan966x with switchdev and vlan support.
The first patches just adds new registers and extend the MAC table to
handle the interrupts when a new address is learn/forget.
The last 2 patches adds the vlan and the switchdev support.

v1->v2:
- when allocating entries for the mac table use kzalloc instead of
  devm_kzalloc
- also use GFP_KERNEL instead of GFP_ATOMIC, because is never called
  in atomic context
- when deleting an mac table entry, the order of operations was wrong
- if ana irq is enabled make sure it gets disabled when the driver is
  removed

Horatiu Vultur (6):
