From: Ben Greear <greearb@xxxxxxxxxxxxxxx>
CT firmware now supports flushing all tids for all
peers for all vdevs. This appears to help the ath10k_flush
logic work faster and not cause timeouts.

This requires the previously-sent patch that enables the
ATH10K_FW_FEATURE_WMI_10X_CT feature bit. This patch provide
a nice improvement in stability and flush performance in my
testing scenarios.
