We are missing the flag that indicates that capability
of 40MHz bandwidth support in HE on the LB.
Add it.

Jouni, I had basically the same patch and I'm going to apply it...

However, it breaks two tests in hostap - according to my earlier
analysis, this is because throughput estimation for HE/EHT doesn't take
the AP *operation* into account, only the *capabilities*.

That's now fixed in hostap.git.
