Subject: [PATCH] iwlwifi: Send DQA enable command only if TVL is on
Git-commit: 79660869bf750b3b52672cbae119e3a1e96a3165
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
The newer targets don't support the DQA enablement command
and will return error status, while older targets need it.
The feature is defined by the corresponding TLV.
Send the command only if the TLV is enabled.
