This adds support for MediaTek MT7615E 4x4 802.11ac PCIe-based chipsets.
In the legacy tx arch, we move and store the whole skb content to the
on-device memory when we send packets via high speed interface. (i.e. PCIe)
However, MT7615 and the following generation use a new tx arch called
“cut-through”, which only passes the physical address to the hardware,
and the packet engine will fetch the packets before transmission.
It saves on-chip memory for high throughput devices, and the token mechanism
is used to manage the release of skb under this arch.
Detailed hardware information for this chip could be found on
https://wikidevi.com/wiki/MediaTek_MT7615

mt76: add unlikely() for dma_mapping_error() check
mt76: use macro for sn and seq_ctrl conversion

This driver is for a newer generation of MediaTek MT7615 4x4 802.11ac
PCIe-based chipsets, which support wave2 MU-MIMO up to 4 users/group
and also support up to 160MHz bandwidth.
The driver fully supports AP, station and monitor mode.

mt76 is under ISC so why did you choose GPLv2 here? I don't think it's a
good idea to use different licenses within the same driver.
Also mt76 does not use SPDX tags yet. I would prefer that the whole
driver is converted in one go to have consistent licensing information.

OK. I will modify it.

mt76x0 is GPL only as some parts of it are modified copy of either out
of tree Mediatek GPL driver or Jakub's mt7601u also realised under GPL.
Is ISC equal to "Dual BSD/GPL" what is marked by MODULE_LICENSE ?
I think this should be clarified too.

Agree. However not sure if we can unify of all mt76 code to the same
license (and which one: GPL ?), but at least we can convert source
files to SPDX identifier.
