From 9e2f3860220280a5630971478b53c8ad9a991ca8 Mon Sep 17 00:00:00 2001 From: Jordan Whited Date: Thu, 2 Mar 2023 15:08:28 -0800 Subject: conn, device, tun: implement vectorized I/O on Linux Implement TCP offloading via TSO and GRO for the Linux tun.Device, which is made possible by virtio extensions in the kernel's TUN driver. Delete conn.LinuxSocketEndpoint in favor of a collapsed conn.StdNetBind. conn.StdNetBind makes use of recvmmsg() and sendmmsg() on Linux. All platforms now fall under conn.StdNetBind, except for Windows, which remains in conn.WinRingBind, which still needs to be adjusted to handle multiple packets. Also refactor sticky sockets support to eventually be applicable on platforms other than just Linux. However Linux remains the sole platform that fully implements it for now.
