Log: Don't re-evaluate ALTQ kernel configuration due to events on non-ALTQ interfaces Re-evaluating the ALTQ kernel configuration can be expensive, particularly when there are a large number (hundreds or thousands) of queues, and is wholly unnecessary in response to events on interfaces that do not support ALTQ as such interfaces cannot be part of an ALTQ configuration.
