8.4.20 Eth_EnableEgressTimeStamp [SWS_Eth_00186] Definition of API function Eth_EnableEgressTimeStamp ⌈ Service Name Eth_EnableEgressTimeStamp Syntax void Eth_EnableEgressTimeStamp ( uint8 CtrlIdx, Eth_BufIdxType BufIdx ) Service ID [hex] 0x17 Sync/Async Synchronous Reentrancy Non Reentrant CtrlIdx Index of the addresses controller. Parameters (in) BufIdx Index of the message buffer, where Application expects egress time stamping Parameters (inout) None Parameters (out) None Return value None Description Activates egress time stamping on a dedicated message object. Some HW does store once the egress time stamp marker and some HW needs it always before transmission. There will be no "disable" functionality, due to the fact, that the message type is always "time stamped" by network design.
