In my imagination it the same. Actually AR9380 Rev 2.2 is the first
commercially available MIMO 3x3 chip. Or I'm be quite wrong?

By the way, after loading the modified driver I reverse changes and install
original driver module, but it does not work with same error.  MSI in PCI
is still enabled and I should to reboot my PC to have it back again.
