poky-gen-tapdevs: script to create a 'bank' of tap interfaces
This script can be used to create and configure a 'bank' of tap
interfaces that can be used by the poky-qemu script.
It is useful in locked-down enterprise environments where developers
do not have sudo access, but need to be able to run QEMU with
networking. A sysadmin would then use this script to bring up a
number of tap interfaces for the user to make use of.
This fixes [BUGID #391]
