Problem wifi -> MT7621 build 21.01.1

1 - snapshot no problem with WIFI 2.4 & 5 GHz

2 - git clone ... ( new folder )
git checkout v21.02.1
After testing I have the impression that the 2 WIFI ports are reversed

The name of the first port (2.4 GHz) is called MediaTek MT7915E 802.11nacax which is weird because it should be bgnax
When i scan the envirronment i see the 5 GHz boxes !!!

For the second ( 5 GHz) which should be nacax I only have bg

Would the driver be different for that to happen ?

Version 21.02.1 may not know WIFI AX ?

I use the same DTS file
