Andrew Gabbasov 68b9f0865b ravb: Fix bit fields checking in ravb_hwtstamp_get() ... In the function ravb_hwtstamp_get() in ravb_main.c with the existing values for RAVB_RXTSTAMP_TYPE_V2_L2_EVENT (0x2) and RAVB_RXTSTAMP_TYPE_ALL (0x6) 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; if the test on RAVB_RXTSTAMP_TYPE_ALL should be true, it will never be reached. This issue can be verified with 'hwtstamp_config' testing program (tools/testing/selftests/net/hwtstamp_config.c). Setting filter type to ALL and subsequent retrieving it gives incorrect value: $ hwtstamp_config eth0 OFF ALL flags = 0 tx_type = OFF rx_filter = ALL $ hwtstamp_config eth0 flags = 0 tx_type = OFF rx_filter = PTP_V2_L2_EVENT Correct this by converting if-else's to switch.
