MT7915E is the latest generation IEEE 802.11ax NIC in MediaTek, which
currently supports AP, Station and Mesh mode.

Even though some code of MT7915[1] are similar to MT7615. New generation has: 
- Huge amounts of HE dedicated parts.
- New designs of PHY/firmware/DMA scheme.
- Most fields of txd/txs/rxd/rxv are rearranged or deprecated.
- Support much more offloading stuff.

Most importantly, for the sake of convenience to get family devices supported
in the future, it was concluded to be simpler to have a clean start for this
generation. This makes maintenance easier and avoids major changes in MT7615,
which currently shares the codes with low power capable device MT7663. It will
increase the risk of regressions in existing flow.

MT7915 supports only basic HE for the moment, whereas other 802.11ax specific
features, such as BSS color, TWT, SR, DCM and OFDMA are work in progress,
and will be gradually added in upcoming days.

The firmwares are available now from https://github.com/ryderlee1110/wireless-fw ,
and will be submitted soon. At last, the developers are all listed in the series.

Thanks,

Changes since v1 -
- list a missing developer.
- drop unused codes in the hw_tx_amsdu patch.
- add a missing bitwidth change of wcid.
- add more TODO items in the driver.

This patchset should be marked as v2, no big deal but just a
clarification. I did have few comments on the real v1 though, please
take a look.
