kernel: add mediatek soc ethernet performance improvements
- implement multiqueue via qdma hardware shaper to deal with ports with different speeds
- implement hardware DSA untagging
- add NETIF_F_ALL_TSO to reduce unnecessary segmentation

+Subject: [PATCH] net: ethernet: mtk_eth_soc: implement multi-queue
+ support for per-port queues
+
+When sending traffic to multiple ports with different link speeds, queued
+packets to one port can drown out tx to other ports.
+In order to better handle transmission to multiple ports, use the hardware
+shaper feature to implement weighted fair queueing between ports.
+Weight and maximum rate are automatically adjusted based on the link speed
+of the port.
+The first 3 queues are unrestricted and reserved for non-DSA direct tx on
+GMAC ports. The following queues are automatically assigned by the MTK DSA
+tag driver based on the target port number.
+The PPE offload code configures the queues for offloaded traffic in the same
+way.
+This feature is only supported on devices supporting QDMA. All queues still
+share the same DMA ring and descriptor pool.
