2023-10-10device: move Queue{In,Out}boundElement Mutex to container typeJordan Whited
Queue{In,Out}boundElement locking can contribute to significant overhead via sync.Mutex.lockSlow() in some environments. These types are passed throughout the device package as elements in a slice, so move the per-element Mutex to a container around the slice.

2023-03-10conn, device, tun: implement vectorized I/O plumbingJordan Whited
Accept packet vectors for reading and writing in the tun.Device and conn.Bind interfaces, so that the internal plumbing between these interfaces now passes a vector of packets. Vectors move untouched between these interfaces, i.e. if 128 packets are received from conn.Bind.Read(), 128 packets are passed to tun.Device.Write(). There is no internal buffering. Currently, existing implementations are only adjusted to have vectors of length one. Subsequent patches will improve that. Also, as a related fixup, use the unix and windows packages rather than the syscall package when possible.

Enabled by using Go 1.18. A bit less verbose. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>

Channels are FIFO which means we have guaranteed cache misses. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2021-01-07device: always name *Queue*Element variables elemJosh Bleecher Snyder
They're called elem in most places. Rename a few local variables to make it consistent. This makes it easier to grep the code for things like elem.Drop. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
