The mlo_capable flag in structure ath12k_hw_group indicate that a device
is capable of operating in multi-link mode. Currently this is enabled
based on single_chip_mlo_support advertised by the firmware within
ath12k_qmi_phy_cap_send().
Since the firmware advertises multi-link operation (MLO) support through
the ATH12K_FW_FEATURE_MLO feature in firmware-2.bin, there is no need to
rely on the QMI phy capability (single_chip_mlo_support). Therefore remove
the dependency on single_chip_mlo_support to set mlo_capable flag.
Below is the impact on single split-phy PCI device with and without this
patch:
Note: This patch does not change the existing behavior of the single
split-phy PCI device.
1. Driver without this patch + firmware with single_chip_mlo_support
as false: MLO is not enabled.
2. Driver without this patch + firmware with single_chip_mlo_support
as true: MLO works fine.
3. Driver with this patch + firmware with single_chip_mlo_support as
false: MLO is not enabled.
4. Driver with this patch + firmware with single_chip_mlo_support as
true: MLO works fine.
