From 2ea4dc28a5bcec408e01a8772763871638a5ec79 Mon Sep 17 00:00:00 2001 From: Alexandre Rames Date: Fri, 8 Nov 2013 10:20:31 +0000 Subject: sfc: Stop/re-start PTP when stopping/starting the datapath. This disables PTP when we bring the interface down to avoid getting unmatched RX timestamp events, and tries to re-enable it when bringing the interface up. [bwh: Make efx_ptp_stop() safe on Falcon. Introduce efx_ptp_{start,stop}_datapath() functions; we'll expand them later.] Fixes: 7c236c43b838 ('sfc: Add support for IEEE-1588 PTP') Signed-off-by: Ben Hutchings --- drivers/net/ethernet/sfc/nic.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/net/ethernet/sfc/nic.h') diff --git a/drivers/net/ethernet/sfc/nic.h b/drivers/net/ethernet/sfc/nic.h index 11b6112d9249..91c63ec79c5f 100644 --- a/drivers/net/ethernet/sfc/nic.h +++ b/drivers/net/ethernet/sfc/nic.h @@ -560,6 +560,8 @@ void efx_ptp_get_ts_info(struct efx_nic *efx, struct ethtool_ts_info *ts_info); bool efx_ptp_is_ptp_tx(struct efx_nic *efx, struct sk_buff *skb); int efx_ptp_tx(struct efx_nic *efx, struct sk_buff *skb); void efx_ptp_event(struct efx_nic *efx, efx_qword_t *ev); +void efx_ptp_start_datapath(struct efx_nic *efx); +void efx_ptp_stop_datapath(struct efx_nic *efx); extern const struct efx_nic_type falcon_a1_nic_type; extern const struct efx_nic_type falcon_b0_nic_type; -- cgit
