When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and
mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will
dereference a NULL WED pointer.
Fix the issue by always passing the WED pointer from mt7996_dma_init().

Introduce Airoha NPU support to MT7996 driver. NPU is 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.

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.

Introduce rx_rro_ind_process and rx_rro_add_msdu_page callbacks and the
related logic in the MT7996 driver. This is a preliminary patch to
decouple RRO logic from WED support and reuse RRO when WED module is not
available.

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().

Some management frames are first processed by the firmware and then
passed to the driver through the MCU event rings. In CONNAC3, event rings
do not support scatter-gather and have a size limitation of 2048 bytes.
If a packet sized between 1728 and 2048 bytes arrives from an event ring,
the ring will hang because the driver attempts to use scatter-gather to
process it.
To fix this, include the size of struct skb_shared_info in the MCU RX
buffer size to prevent scatter-gather from being used for event skb in
mt76_dma_rx_fill_buf().
