Compiling MT76 on CURRENT

Hello,

I read that this driver was added to base and I can find the source but I
don't know how to compile it, because I don't get /boot/kernel/if_mt*.ko
and I couldn't grep/find the tunable that enables building of this
driver. Is there any doc that can tell me how to try it out? I know it's
experimental and I have a laptop that has this wifi ready for
experiments.

Regards,
meka
