[PATCH 1/2] wifi: ath12k: extend the link capable flag

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Link capability categorized as Single Link Operation (SLO) and Multi Link
Operation (MLO).

	* Intra-chip SLO/MLO refers to links present within a chip
	* Inter-chip SLO/MLO refers to links present across multiple chips

Currently, driver uses a boolean variable to represent intra-chip SLO/MLO
capability. To accommodate inter-chip SLO/MLO capabilities within the same
variable, modify the existing variable name and type. Define a new
enumeration for the link capabilities to accommodate both intra-chip and
inter-chip scenarios. Populate the enum based on the supported
capabilities.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
