Commit Message

Ryder Lee April 1, 2019, 6:56 a.m. UTC
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.

Changes since v2:
-switch to use ISC license
-use sw assign sequence number
-add missing hw rate setting
