This function returns T if the given name is a macvtap device. This is determined by 1) getting the ifindex of the device with that name (if there is one), and 2) checking for existence of /dev/tapXX, where "XX" is the ifindex learned in (1).
It's also possible to learn this by getting a netlink dump of the interface and parsing through it to look for some attributes, but that is complicated to figure out, takes longer to execute, and I'm lazy.
