[PATCH v2 0/2] net: ethernet: mtk_eth_soc: use WO firmware for MT7981

[Daniel Golle]

In order to support wireless offloading on MT7981 we need to load the
appropriate firmware. Recognize MT7981 by introducing a new DT compatible
and load mt7981_wo.bin if it is set.

Changes since v1:
 * retain alphabetic order in dt-bindings

[PATCH v2 1/2] dt-bindings: net: mediatek: add WED RX binding for MT7981 eth driver

[Daniel Golle]

Add compatible string for mediatek,mt7981-wed as MT7981 also supports
RX WED just like MT7986, but needs a different firmware file.
