// The following bits are added to packet marks for Tailscale use.
//
// We tried to pick bits sufficiently out of the way that it's
// unlikely to collid with existing uses. We have 4 bytes of mark bits
// to play with. We leave the lower byte alone on the assumption that
// sysadmins would use those. Kubernetes uses a few bits in the second
// byte, so we steer clear of that too.

// Empirically, most of the documentation on packet marks on the
// internet gives the impression that the marks are 16 bits
