Hello Jeff,

Thanks for the link.  That too is dual band though.  I'm interested in
using ath12k radios for wifi testing purposes, so I'd really like tri-band
MLO to have some feature parity with the MTK 7996 radio board.

Is ath12k able to combine discrete wifi NICs into tri-band MLO stations?

Or is ath12k entirely DBDC at this point with no tri-band MLO capability?

In addition, back in ath10k days, I was able to get the radio to do up to
64 STA vdevs once I put the firmware on a diet.  From a quick look at the ath12k
driver, it seems the limit for STA vdevs is exactly 1.  Is there any somewhat-documented
way to get ath12k to support more STA vdevs?

Thanks,
Ben
