Kernel 5.8.13-arch1-1 and TBS6981

Hello,

My system has 5.8.13 kernel and it detects the TBS 6981 card,

Unfortunately, if i try to do a blind scan with w_scan2 i get messages that "freq 6.21 unsupported by driver: min=0.95, max=2.15". Is this frequency a limitation of the opensource driver?

I was able to get this going after updating the frequency table.
