Hello, In the function ravb_hwtstamp_get in ravb_main.c, the following code looks suspicious: if (priv->tstamp_rx_ctrl & RAVB_RXTSTAMP_TYPE_V2_L2_EVENT) config.rx_filter = HWTSTAMP_FILTER_PTP_V2_L2_EVENT; else if (priv->tstamp_rx_ctrl & RAVB_RXTSTAMP_TYPE_ALL) config.rx_filter = HWTSTAMP_FILTER_ALL; else config.rx_filter = HWTSTAMP_FILTER_NONE; According to drivers/net/ethernet/renesas/ravb.h, RAVB_RXTSTAMP_TYPE_V2_L2_EVENT is 0x00000002 and RAVB_RXTSTAMP_TYPE_ALL is 0x00000006. Therefore, if the test on RAVB_RXTSTAMP_TYPE_ALL should be true, it will never be reached. How should the code be changed? thanks, julia
