Max STA for Intel AX201

[benoit at neviani.fr]

Hi, 

I have time to time a lot of "IEEE 802.11: Could not add STA to kernel driver" and I am not able to connect to the AP anymore with a AP Full message.
I know that most of the wireless cards have a limit, and I am crossing the limit (I think around 10 for my card).

Is there a way to know the limit ? My card is a Intel(R) Wi-Fi 6 AX201.

My real issue, is that even if I disconnect a bunch of clients, I am not able to connect anymore unless I restart hostapd service, if you have any idea on how to "release" them.

Many thanks
