Subject: [PATCH 77/91] net: mediatek: do not set the QID field in the TX DMA
descriptors
The QID field gets set to the mac id. This made the DMA linked list queue
the traffic of each MAC on a different internal queue. However during long
term testing we found that this will cause traffic stalls as the multi
queue setup requires a more complete initialisation which is not part of
the upstream driver yet.
This patch removes the code setting the QID field, resulting in all
traffic ending up in queue 0 which works without any special setup.

Subject: [PATCH 81/91] net-next: mediatek: add fixed-phy support
The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1
needs to be configured using a fixed link speed and flow control settings.
The easiest way to do this is to used the fixed-phy driver, allowing us to
reuse the existing mdio polling code to setup the MAC.

Subject: [PATCH 87/91] net-next: mediatek: add IRQ locking
The code that enables and disables IRQs is missing proper locking. After
adding the IRQ separation patch and routing the putting the RX and TX IRQs
on different cores we experienced IRQ stalls. Fix this by adding proper
locking. We use a dedicated lock to reduce the latency if the IRQ code.
Otherwise it might wait for bottom code to finish before reenabling or
disabling IRQs.

Subject: [PATCH 88/91] 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.
