Really, the frequence offset is zero (or at least less that 1 ppb!). The very first Sync message gives the phase offset, and after that first jump both offsets stay zero forever. The option is supposed to tell ptp4l, just set the frequency offset to zero and then leave it there. Actually, the reseting to zero is important, just in case a previous run without SyncE had set some offset.
