Summary

Planned commit message:

wtap(4): Rename physical interface

The original physical interface created by wtap is "wlan%d", which will confuse us with the vap created by ifconfig which also named "wlan%d". Rename the physical interface to "wtap%d".

This diff depends on D35624.

why? it's designed to be used as an emulator / virtual 802.11 interface for building tests. :-) So it should be wlanX.

But we still need to create a wlan interface to use it so the full commands are like:

./wtap c 0
ifconfig wlan0 create wlandev wlan0 wlanmode mesh

Then we have a wlan0 with parent wlan0, looks a bit odd to me. That's why I suggest to do this change. But this could be my misunderstanding, if so, sorry for the noise.

I wonder if this is how it used to be in the deep, distant past. ok, this is right!

Even in a deep distant past, this wasn't right; someone just knew what they were doing. Sadly there isn't much/any documentation from that time when the code was committed, is there?
