Subject: [PATCH 1/3] Fix virtual drive auto-renaming

In some Linux distributions (e.g. Ubuntu, Debian), udev automatically renames any device with its name prefix is "eth*", "wlan*",... as declared in "/lib/udev/rules.d/75-persistent-net-generator.rules". This made a problem when creating a virtual device on these distributions declaring that device not found. Solution was to change virtual device's name prefix to "ap*" to avoid this collision.
