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.
Well right now the socket is only used within the kernel by
vhost so it's not exported to user-space. If we were to use
recvmmsg obviously we'd create a new interface based on sockets
for tun and expose the existing socket through that.
Ah, that explains it then. I was afraid I was just going insane :)
The current file-based tun interface was never designed to be
a high-performance interface. So let's take this opportunity
and create a new interface (but still using the same underlying
code since whatever you create should be easily applicable to
the existing kernel user vhost).
Sounds good to me. I'll get a patch turned around soon.
Thanks,
