The function ixgbe_ptp_setup_sdp_X540 attempts to program a software defined pin, in order to generate a pulse-per-second output on SDP 0. It does work to generate the output, but does not align the output on the full second. Additionally, it does not take into account the cyclecounter multiplier. This leads to somewhat confusing code which is likely to be incorrect if blindly copied to another hardware type. Update this code to account for the cyclecounter multiplier, and to directly use timecounter_read. This change ensures that the SDP output will align properly on a full second, and makes the intent of the calculations a bit more clear.
