Ryder Lee March 26, 2019, 2:28 p.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.

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.
