* conn: inch BatchSize toward being non-dynamicJason A. Donenfeld2023-03-101-1/+1
| | | | | | | | There's not really a use at the moment for making this configurable, and once bind_windows.go behaves like bind_std.go, we'll be able to use constants everywhere. So begin that simplification now. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* conn, device, tun: implement vectorized I/O on LinuxJordan Whited2023-03-101-1/+3
| | | | | | | | | | | | | | | | | | | | 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.
