Hey Herbert, Thanks for getting back to me

As tun already has a socket interface can we do this through recvmmsg?
This just presents an easier interface (IMHO) for accomplishing that. And I say easier because I was unable how to figure out the recvmmsg way to do it.
While fully aware that this makes me look like an idiot, I have to admit that I've tried and failed to figure out how to get a socket fd out of the tun device.
The regular fd doesn't work (which is obvious when you look at the implementation sock_from_file), there's a tun_get_socket function but it's only referenced by a single file, and none of the ioctl's jump out at me as doing anything to enable this behavior. Additionally, tuntap.txt makes no mention of sockets specifically.
FWIW, I don't feel strongly that IFF_MULTI_READ is the right way to do this either.
