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.

conn: inch BatchSize toward being non-dynamic 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.

device: ratchet up max segment size on android GRO requires big allocations to be efficient. This isn't great, as there might be Android memory usage issues. So we should revisit this commit. But at least it gets things working again. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> 2023-10-22 02:12:13 +02:00			`MaxSegmentSize = (1 << 16) - 1 // largest possible UDP datagram`
