For 82576 MAC type, max_adj is reported as 1000000000 ppb. However, if this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping the PHC (instead of going at twice the nominal speed). Fix the advertised max_adj value to the largest value hardware can handle. As there is no min_adj value available (-max_adj is used instead), this will also prevent stopping the clock intentionally. It's probably not a big deal, other igb MAC types don't support stopping the clock, either.
