This is astronomically long compared to the worst case\ntimings expected by our devices. In addition, this is longer than the\nwait in ptp4l when it detects a fault (caused by missing Tx timestamps).\nThus, reduce the timer to only 1 second, which is well after the maximum\nexpected delay. This should reduce user frustration when a timestamp\ndoes get dropped for some reason.\n\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\n---\n drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c b/drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c\nindex d81a50dc9535..dbe84a4d2f7f 100644\n--- a/drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c\n+++ b/drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c\n@@ -72,7 +72,7 @@\n #define IXGBE_INCPER_SHIFT_82599 24\n \n #define IXGBE_OVERFLOW_PERIOD (HZ * 30)\n-#define IXGBE_PTP_TX_TIMEOUT (HZ * 15)\n+#define IXGBE_PTP_TX_TIMEOUT (HZ)\n \n /* half of a one second clock period, for use with PPS signal.
