[PATCH v2 00/18] Add MediaTek IEEE 802.11ax devices - MT7915E

[Ryder Lee]

MT7915E[1] is MediaTek latest generation IEEE 802.11ax device, which
currently supports AP, Station and Mesh mode.

Even though some code of MT7915 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 are work in progress.(e.g. BSS color, TWT, SR, OFDMA and DCM)
They will be gradually added in upcoming days.

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

Thanks,
Ryder

Changes since v2 -
- drop hw_amsdu patch
- fix kconfig license
- fix debugfs regard to txpower dump issue
- swtich to use "per-phy" to set runtime stream caps for dual band concurrent operation.
- move omac_idx to mt7915_phy to make it independent
- add .get/set_tsf callbacks

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.

[PATCH v2 06/18] mt76: add mac80211 driver for MT7915 PCIe-based chipsets

[Ryder Lee]

Add support for the MediaTek latest generation IEEE 802.11ax 4x4
device MT7915E, which supports concurrent dual-band operation at
both 5GHz and 2.4GHz.

Note that this patch just add basic part and will add more HE
capabilities support in the further patches.

The driver supports AP, Station, Mesh and monitor mode.

[PATCH v2 06/18] mt76: add mac80211 driver for MT7915 PCIe-based chipsets

[Ryder Lee]

Add support for the MediaTek latest generation IEEE 802.11ax 4x4
device MT7915E, which supports concurrent dual-band operation at
both 5GHz and 2.4GHz.

Note that this patch just add basic part and will add more HE
capabilities support in the further patches.

The driver supports AP, Station, Mesh and monitor mode.

[PATCH v2 09/18] mt76: mt7915: register per-phy HE capabilities for each interface

[Ryder Lee]

The capabilities for the HE interfaces are generated from the capabilities
reported by the firmware.

This should move to common file once we got other HE devices support.

[PATCH v2 09/18] mt76: mt7915: register per-phy HE capabilities for each interface

[Ryder Lee]

The capabilities for the HE interfaces are generated from the capabilities
reported by the firmware.

This should move to common file once we got other HE devices support.

[PATCH v2 10/18] mt76: mt7915: add HE bss_conf support for interfaces

[Ryder Lee]

Add basic HE BSS's info for interfaces. As for the advanced features
will be added gradually in the future patches.
(i.e. BSS color, TWT, spatial reuse and OFDMA)

[PATCH v2 13/18] mt76: mt7915: add .sta_add_debugfs support

[Ryder Lee]

This generation supports much more per-peer statistics than legacy ones,
so add .sta_add_debugfs accordingly.

This is convenient to set/get more settings/counters in the long run.

[PATCH v2 15/18] mt76: mt7915: set peer Tx fixed rate through debugfs

[Ryder Lee]

Driver can manually set fixed rate for each peer through debugfs.

May use .set_bitrate_mask callback and iterate stations under the
current vif to achieve the aim once it supports HE rate.

[PATCH v2 15/18] mt76: mt7915: set peer Tx fixed rate through debugfs

[Ryder Lee]

Driver can manually set fixed rate for each peer through debugfs.

May use .set_bitrate_mask callback and iterate stations under the
current vif to achieve the aim once it supports HE rate.
