My results with VMs are much better with the TX control, and I think it can help baremetal too. Any feedback on v7, anything else I can do? At least, would it be acceptable for ath11k? For ath12k, if the concern is the locking, the rcu_dereference_bh refactoring would require changes to existing mac_op_tx code. Is that the direction you want? Thanks Best regards José Ignacio
