From e9523a5a32a1ce3acfe875cddd8ac8ad8a9ed270 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Thu, 8 Jun 2017 13:51:31 -0500 Subject: [PATCH] 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 Signed-off-by: David S.
