This Counter32 tracks the number of incoming packets on the MP link that arrived out of order and had to be reordered. An admin monitors this to gauge how much jitter or latency variance exists across the bundle's member channels, since packets traveling different physical links can arrive in a different order than sent. For example, a high hpnicfMpReorderedPktsV2 relative to total traffic would suggest the bundled member links have mismatched latency, worth checking for one slower or congested channel.
