Miller" , , Sekhar Nori CC: , , Grygorii Strashko Subject: [PATCH] cpsw: cpts: enable HWTSTAMP_FILTER_PTP_V1_L4_EVENT filter Date: Mon, 5 Jun 2017 18:21:08 -0500 Message-ID: <20170605232108.13453-1-grygorii.strashko@ti.com> X-Mailer: git-send-email 2.10.1 MIME-Version: 1.0 Sender: linux-omap-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-omap@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP 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.
