[PATCH 0/4] Add support for MediaTek MT7615 wireless chipsets

[Ryder Lee]

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

  mt76: add mac80211 driver for MT7615 PCIe-based chipsets
  mt76: add unlikely() for dma_mapping_error() check
  mt76: use macro for sn and seq_ctrl conversion
