Lorenzo BianconiandFelix Fietkau 1e91eadc9d wifi: mt76: wed: use proper wed reference in mt76 wed driver callabacks
MT7996 driver can use both wed and wed_hif2 devices to offload traffic
from/to the wireless NIC. In the current codebase we assume to always
use the primary wed device in wed callbacks resulting in the following
crash if the hw runs wed_hif2 (e.g. 6GHz link).

Alok TiwariandFelix Fietkau 4e7077f774 wifi: mt76: mt7996: fix FCS error flag check in RX descriptor
The mt7996 driver currently checks the MT_RXD3_NORMAL_FCS_ERR bit in
rxd1 whereas other Connac3-based drivers(mt7925) correctly check this
bit in rxd3.

Since the MT_RXD3_NORMAL_FCS_ERR bit is defined in the fourth RX
descriptor word (rxd3), update mt7996 to use the proper descriptor
field. This change aligns mt7996 with mt7925 and the rest of the
Connac3 family.

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().
