What else is required to get this working? I used ath11k-bringup (which 
included these patches) and wanted to implement the HE registration part for 
it. But it turns out that it doesn't event work here with VHT. This is what I 
did on two HK01 rev B:

    iw phy phy2 interface add mesh2 type mp
    ip link set up dev mesh2
    iw dev mesh2 mesh join testmesh freq 5180 80MHz

But the firmware just crashes somewhere around the association phase:

The whole device goes down after that.

Kind regards,
