Most of these changes come from OpenWrt where they have been present and
tested for months.

First three patches are bug fixes. The rest are performance
improvements. The last patch is a cleanup to use the iopoll.h macro for
busy-waiting instead of a custom loop.

Source: 770-*.patch at https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=target/linux/generic/pending-5.10;hb=HEAD

  net: ethernet: mtk_eth_soc: reduce MDIO bus access latency
  net: ethernet: mtk_eth_soc: remove unnecessary TX queue stops
  net: ethernet: mtk_eth_soc: use larger burst size for QDMA TX
  net: ethernet: mtk_eth_soc: increase DMA ring sizes
  net: ethernet: mtk_eth_soc: implement dynamic interrupt moderation
  net: ethernet: mtk_eth_soc: cache HW pointer of last freed TX
    descriptor

Do you have any benchmark numbers you can share?

No. Felix, do you have anything handy?

If needed, I'll run some tests before and after the patch series on
OpenWrt against v5.10, but I only have an MT7621 device - should be
better than nothing though...
