Subject: iwlwifi: mvm: BT Coex - relax constraints when TTC / RRC is active
X-Git-Tag: v3.17-rc1~106^2~210^2~29
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=4c86f938d359f30a52134d3fc9945f95a3e621e2;p=~emulex%2Finfiniband.git

iwlwifi: mvm: BT Coex - relax constraints when TTC / RRC is active

When TxTxCo-Running is active, we can relax the constraints
on the rate control.
When RxRxCo-Running is active, we can relax the constrains
on SMPS.
