    Subject[PATCH 6.0 339/862] eth: lan743x: reject extts for non-pci11x1x devices
    Date
    From: Raju Lakkaraju <Raju.Lakkaraju@microchip.com>

    [ Upstream commit cb4b12071a4b68df323c339f60805834246b3e9e ]

    Remove PTP_PF_EXTTS support for non-PCI11x1x devices since they do not support
    the PTP-IO Input event triggered timestamping mechanisms added

    Fixes: 60942c397af6 ("net: lan743x: Add support for PTP-IO Event Input External Timestamp (extts)")
