HA ignored packets cause DROP statistics counter increment

HA_BUFFER6_RECEIVE_NOT_FOR_US increments drop counters.

  • This happens at least with a load balancing configuration.
  • I think maybe not with hot-standby since I don't think the service logs anything or cares about incoming client packets unless it loses contact with the HA peer?
  • I cite BUFFER6 above but I'm sure the same is true for DHCPv4.

Possible solutions:

  • introduce a new drop status that could be discounted later or part of a different drop statistic?
  • Could introduce new status that it is ignored or filtered instead of dropped?
