When transmitting to a receiver in dynamic SMPS mode, all transmissions that use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to give the receiver's extra chains some time to wake up. This fixes the tx rate getting stuck at <= MCS7 for some clients, especially Intel ones, which make aggressive use of SMPS.

No Fixes tag so I assume this is not a regression? Should this go to v5.12 or -next? I guess that depends how much testing this patch has got. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
