This series adds initial EHT support for mt7996 driver, which currently
covers features of EHT SU mode. More EHT features are work in progress
and will be introduced in further patches.

This series is based on the following series:
- wifi: mt76: mt7996: fix chainmask calculation in mt7996_set_antenna()
  https://patchwork.kernel.org/project/linux-wireless/patch/20221223101348.11504-1-shayne.chen@mediatek.com/

v2:
  - add eth param to mt76_ethtool_worker() to prevent from breaking HE stats

Currenly only EHT TX rate report is supported. EHT RX rate is temporally
reported with HE rate.
