Subject: [PATCH 73/78] net-next: mediatek: add support for IRQ grouping
The ethernet core has 3 IRQs. using the IRQ grouping registers we are able
to separate TX and RX IRQs, which allows us to service them on separate
cores. This patch splits the irq handler into 2 separate functiosn, one for
TX and another for RX. The TX housekeeping is split out of the NAPI handler.
Instead we use a tasklet to handle housekeeping.
