static void ptp_commence_p2p_correction ( uint32_t  pdelRespSeqId )

static

Initiate the P2P correction. This piece of code has been extracted from the ptp_slave_process_message() to prevent code duplication.

Parameters

pdelRespSeqId

sequence ID of the last completed PDel_Req...PDel_Resp(_Follow_Up) cycle

Definition at line 287 of file slave.c.
