Pick patches with several fixes and improvements, preparation for upcoming WED (TX) [1] as well as basic XDP support [2] with MediaTek's Filogic SoCs to the mtk_eth_soc driver. Also pick follow-up patch fixing Ethernet on MT7621 [3]. Tested on Bananapi BPi-R3 (MT7986), Bananapi BPi-R64 (MT7622), Bananapi BPi-R2 (MT7623), MikroTik RouterBoard M11G (MT7621). [1]: https://patchwork.kernel.org/project/netdevbpf/list/?series=662108&state=* [2]: https://patchwork.kernel.org/project/netdevbpf/list/?series=675368&state=* (the first part of the series adding wed nodes to mt7986a.dtsi was applied to the copy of mt7986a.dtsi in our tree) [3]: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=5e69163d3b9931098922b3fc2f8e786af8c1f37e Signed-off-by: Daniel Golle <daniel@makrotopia.org>
