SKB_SHARED_HW(9) 					 Linux Networking					   STRUCT SKB_SHARED_HW(9)

NAME
       struct_skb_shared_hwtstamps - hardware time stamps

SYNOPSIS
       struct skb_shared_hwtstamps {
	 ktime_t hwtstamp;
	 ktime_t syststamp;
       };

MEMBERS
       hwtstamp
	   hardware time stamp transformed into duration since arbitrary point in time

       syststamp
	   hwtstamp transformed to system time base

DESCRIPTION
       Software time stamps generated by ktime_get_real are stored in skb->tstamp. The relation between the different kinds of time

STAMPS IS AS FOLLOWS
       syststamp and tstamp can be compared against each other in arbitrary combinations. The accuracy of a syststamp/tstamp/"syststamp from other
       device" comparison is limited by the accuracy of the transformation into system time base. This depends on the device driver and its
       underlying hardware.

       hwtstamps can only be compared against other hwtstamps from the same device.

       This structure is attached to packets as part of the skb_shared_info. Use skb_hwtstamps to get a pointer.
