Yes, I agree.

Someone pointed out to me off-list that these corrections are standardized, and they are *not* part of the delayAsymmetry field. In 802.1AS they are defined in Section 8.4.3 as "egressLatency" and "ingressLatency", and 1588 uses an almost identical definition. I will respin this series to make the configuration options have the same names as in the standards.
