net: ethernet: ti: cpsw: enable HWTSTAMP_FILTER_PTP_V1_L4_EVENT filter
CPSW driver supports PTP v1 messages, but for unknown reasons this filter is not advertised. As result, ./tools/testing/selftests/networking/timestamping/timestamping utility can't be used for testing of CPSW RX timestamping with option SOF_TIMESTAMPING_RX_HARDWARE, because it uses HWTSTAMP_FILTER_PTP_V1_L4_SYNC filter. Hence, fix it by advertising HWTSTAMP_FILTER_PTP_V1_L4_XXX filters in CPSW driver. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
