I have patches for wpa_supplicant to handle hotplugging of network interfaces 
on BSD. However, upstream currently think that something else should hotplug 
wpa_supplicant (which is odd as it's wpa_supplicant already has a lot of code 
for hotplugging). The other issue is that there is only 1 driver for BSD 
whereas Linux has quite a few and they wouldn't interact nicely with each 

dhcpcd already handles hotplugging network interfaces.
