I had.

It's perfectly acceptable and already uses netif_<level> properly.

This consolidation now introduces the _only_ instance where it is
now improperly using a netif_msg_<type> then single pr_<level>
function sequence that should be consolidated into netif_dbg.

Every other use of netif_msg_<level> then either emits multiple
lines or is used in an if/else.
