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).

Subject: [PATCH] net: ethernet: mtk_eth_soc: enable threaded NAPI
|
|
|
|
This can improve performance under load by ensuring that NAPI processing is
|
|
not pinned on CPU 0.
