Framed send fails with "Socket operation on non-socket"

[nmldiegues]

Reproduced by using https://github.com/meh/rust-tun/blob/master/examples/ping-tun.rs

When I ping 10.0.0.2, that program gets an ICMP packet, and it tries to reply. At that point it fails in https://github.com/meh/rust-tun/blob/master/examples/ping-tun.rs#L66 with code 88, Socket operation on non-socket

This is happening on Linux Ubuntu 20.04 with Kernel 5.13.0-44 , in case that is relevant for reproducibility.

Just noticed #43 --- this is likely a duplicate, let me try that fix.

Confirmed that #43 fixes this

Can the package be updated in https://crates.io/crates/tun ?
Seems like it was last updated 10 months ago, and that release contains this bug.
