kernel: pick patches for MediaTek Ethernet from linux-next
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).

(the first part of the series adding wed nodes to mt7986a.dtsi was
applied to the copy of mt7986a.dtsi in our tree)
