Yes. You can parse the kernel log for my commits.
I haven't seen a single one that uses netif_*() for logging. On the other hand, almost every single one has a similar module parameter or debugfs knob for enabling different types of debug messages. As it stands, the NETIF_* categories don't really align at all with the kinds of message categories most WiFi drivers support. Do you propose adding a bunch of new options to the netif debug feature?
Why not? It make no sense or it is just "it is tradition, we never do it!" ? Even dynamic printk provide even more granularity. So module parameter looks like stone age against all existing possibilities.
