[Arm-netbook] WiFi oddity on Arm netbook

[Luke Kenneth Casson Leighton]

ahhh... it mayyyy be that .... ok, it would be very funny if your
machine _did_ actually have two PCI-e Ralink 2070s in it :)

where's that.... where is the persistent eth interfaces?  somewhere
stupid in /lib/udev .... got it

 /etc/udev/rules.d/70-persistent-net.rules

 check that that file exists, and if it does, delete it.
