int igb_ptp_hwtstamp_ioctl	(	struct net_device *	netdev,
		struct ifreq *	ifr,
		int	cmd
	)

igb_ptp_hwtstamp_ioctl - control hardware time stamping : : :

Outgoing time stamping can be enabled and disabled. Play nice and disable it when requested, although it shouldn't case any overhead when no packet needs it. At most one packet in the queue may be marked for time stamping, otherwise it would be impossible to tell for sure to which packet the hardware time stamp belongs.

Incoming time stamping has to be configured via the hardware filters. Not all combinations are supported, in particular event type has to be specified. Matching the kind of event packet is not supported, with the exception of "all V2 events regardless of level 2 or 4".

void igb_ptp_init ( struct igb_adapter * adapter )

Definition at line 665 of file igb_ptp.c.

void igb_ptp_reset ( struct igb_adapter * adapter )

igb_ptp_reset - Re-enable the adapter for PTP following a reset. : Board private structure.

This function handles the reset work required to re-enable the PTP device.

void igb_ptp_rx_hwtstamp	(	struct igb_q_vector *	q_vector,
		union e1000_adv_rx_desc *	rx_desc,
		struct sk_buff *	skb
	)

void igb_ptp_stop ( struct igb_adapter * adapter )

igb_ptp_stop - Disable PTP device and stop the overflow check. : Board private structure.

This function stops the PTP support and cancels the delayed work.

Definition at line 773 of file igb_ptp.c.

void igb_ptp_tx_hwtstamp ( struct igb_adapter * adapter )

igb_ptp_tx_hwtstamp - utility function which checks for TX time stamp : Board private structure.

If we were asked to do hardware stamping and such a time stamp is available, then it must have been for this skb here because we only allow only one such packet into the queue.

Definition at line 429 of file igb_ptp.c.

void igb_ptp_tx_work ( struct work_struct * work )

igb_ptp_tx_work : pointer to work struct

This work function polls the TSYNCTXCTL valid bit to determine when a timestamp has been taken for the current stored skb.
