Could somebody provide background information on why the decision was
made to use a second address for the netlink frames instead of the same
address as was used for the non-netlink frames? 

I too have an obscure user-space app which uses this API :)

My app was written to account for both the old and new logic being debated,
so I can cope either way with the flip of a switch. I would just like to
say that for my purposes the patch worked better as I already intended for
my app to track MAC address changes made by a user.

I should note that I am passing these frames between virtual machines so
the use of unique addresses (instead of hard-coded 0x42 addresses) as a key
simplifies things when determining which radio transmitted a given frame
and which radio needs to receive the frame. My app has always relied on the
MAC address assigned by the user as a unique key across virtual machines.
Also, I will point out that I am not using multiple vifs on a radio but if
I were, I imagine that I would send a copy of the frame to each vif.
