[Fix]
From stable updates:
commit c1c1039135c3 ("wifi: iwlwifi: increase number of RX buffers for EHT
devices")
increase number of RX buffers for new wifi card BE200, it needs one more
commit to support the bigger queue's RB status / write pointer.
[Test]
Tested on hardware, Intel BE200 works fine after stress with iperf3 for 20
mins.
[Where problems could occur]
It may break Intel wifi driver.
