Subject: iwlwifi: mvm: BT Coex - don't limit rate control if TTC is on
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=35fbf5d08e57cb4e7bd516781ba9499ff83688f6;p=openwrt%2Fstaging%2Fblogic.git

iwlwifi: mvm: BT Coex - don't limit rate control if TTC is on

When the firmware enables TxTxCorunning, we can lift the
constaints on the rate control.
