Hi Aditya, > Recently MLO CSA is enabled on the stack.

I'll probably drop a 'return -EINVAL' on the warning case, but no need to resend for that. I also wanted to ask though if this needed any hostapd changes? And I guess for real multi-link we need the CSA update things we've been discussing, I'm guessing you're not going to want to work on that in either hostapd or kernel since the ath12k firmware handles it all, right? Thanks, johannes
