====================
Introduce PHY mode 10G-QXGMII

This patch series adds 10G-QXGMII mode for PHY driver. The patch
series is split from the QCA8084 PHY driver patch series below.
https://lore.kernel.org/all/20231215074005.26976-1-quic_luoj@quicinc.com/

Per Andrew Lunn’s advice, submitting this patch series for acceptance
as they already include the necessary 'Reviewed-by:' tags. This way,
they need not wait for QCA8084 series patches to conclude review.

Changes in v2:
	* remove PHY_INTERFACE_MODE_10G_QXGMII from workaround of
	  validation in the phylink_validate_phy. 10G_QXGMII will
	  be set into phy->possible_interfaces in its .config_init
	  method of PHY driver that supports it.
