Recently MLO CSA is enabled on the stack. Add test infra support in
mac80211_hwsim in order to support basic MLO CSA test case.

Aditya Kumar Singh (2):
  wifi: mac80211: check beacon countdown is complete on per link basis
  wifi: mac80211_hwsim: add support for switch_vif_chanctx callback
---
v3: proper patch in [2/2].

v2: handled all mode cases of channel contexts in [2/2].

Can't apply this right now as we're pushing wireless-next up to net-
next, but looks fine to me. 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

Sure, thanks.

Yes there is hostapd test case to validate MLO CSA. Will get those for 
review to Jouni soon.

Yeah at least template update for partner links, not really inclined 
there but I like the idea of controlling it via some flag as you 
suggested so that driver can choose. Currently checking with team 
internally on how to do that. We'll get back soon :) We do have some 
points to add to the discussion thread, will send that as well.

Here you go - "tests: Add basic MLO CSA test case"
(https://patchwork.ozlabs.org/project/hostap/patch/20240308043508.14853-1-quic_adisi@quicinc.com/)

Sorry, got little bit delayed :)
