Details

OS Approach
Linux socket(AF_NETLINK, SOCK_RAW | SOCK_CLOEXEC, NETLINK_ROUTE)
BSD-based Uses of sysctl to retrieve network interfaces
Windows GetAdaptersAddresses

Why a new network interfaces crate?

Because all of current network interfaces crates do not support fetching MTU, and almost all of them are using libc::getifaddrs. This crate tries to avoid unneeded allocation and use more underlying method to achieve the same functionalities.
