The first bottleneck of openvpn is that the Tun character device reads and writes frames at one link layer. The reason why the user-mode openvpn process must have the same link-MTU on both ends, it is because each time openvpn reads a complete Ethernet frame from the/dev/NET/TUN character device, there are not many, and the library interface: ssize_t read (int fd
