net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch (WED)
The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be configured to intercept and handle access to the DMA queues and PCIe interrupts for a MT7615/MT7915 wireless card. It can manage the internal WDMA (Wireless DMA) controller, which allows ethernet packets to be passed from the packet switch engine (PSE) to the wireless card, bypassing the CPU entirely. This can be used to implement hardware flow offloading from ethernet to WLAN. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: David S. Miller <davem@davemloft.net>
