With CONFIG_WIRELESS_OLD_REGULATORY=y, both the old and the new firmware
works. Without, only the old firmware works.

I'd think that at least the error message could be clarified a bit
(is it really a "Microcode SW error"?)... also, it might be a corner case
whether the new firmware would better be called -2 because of this
incompatibility?

Best,
