Lorenzo BianconiandFelix Fietkau 9ccd49d455 wifi: mt76: Do not reset idx for NPU tx queues during reset
Do not run reset_q callaback with reset_idx set to true for NPU Tx
queues. This is a preliminary patch to properly manage reset procedure
when NPU offloading is enabled.

Lorenzo BianconiandFelix Fietkau 141a815570 wifi: mt76: Introduce the NPU generic layer
Add the NPU generic layer in mt76 module. NPU will be used to enable
traffic forward offloading between the MT76 NIC and the Airoha ethernet one
available on the Airoha EN7581 SoC using Netfilter Flowtable APIs.

Felix Fietkau 33f29d2345 wifi: mt76: relicense to BSD-3-Clause-Clear
MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear,
in order to improve clarity and the legal integrity of the code.

The BSD-3-Clause license includes the "no endorsement" clause, which is
important for protecting the reputation of the original authors and
contributors by preventing unauthorized use of their names for endorsement
purposes.

This clause is absent in the BSD-2-Clause license, which is more permissive
but lacks this specific protection.

This change also cleans up the license of some Kconfig/Makefile files,
which were accidentally marked as GPL.

The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615
for which the license situation still needs to be clarified.

Breno LeitaoandFelix Fietkau ef2468830f wifi: mt76: un-embedd netdev from mt76_dev
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_devices from struct mt76_dev by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev_dummy() to allocate the net_device object at
mt76_dma_init().

The free of the device occurs at mt76_dma_cleanup().
