Ah.. I was not looking at this closely enough. This start.sh change does
not actually do anything for my main test setup, since I use a VM and a
kernel without any modules..

I can see this now with vm/vm-run.sh handling the support_p2p_device
modification.

Now that I can reproduce this issue, lets try to figure out what's the
best way of addressing this. Your patch is doing quite a bit more than
just modifying the specfici CTRL-EVENT-REGDOM-CHANGE event. Was there a
reason for doing that or is that all just trying to make these test
cases pass? Would the simpler patch that Ilan sent today work for the
cases where you can see this issue with remote hosts? It is simply
finding the highest level parent to get the IFNAME=wlan0 style prefix
for the event regardless of whether the P2P Device interface is used.
