Overview

This package provides a sideband control interface to an XETH driver. Usage, 

task, err := xeth.Start(dev)
if err {
	panic(err)
}
task.DumpIfInfo()
for t = true; t; {
	select {
	case <-goes.Stop:
		return
	case buf := <-task.RxCh:
		if t = xeth.Class(buf) != xeth.ClassBreak; t {
			msg := xeth.Parse(buf)
			...
			xeth.Pool(msg)
		}
	}
}
...
task.DumpFib()
for t := true; t; {
	select {
	case <-goes.Stop:
		return
	case buf := <-task.RxCh:
		if t = xeth.Class(buf) != xeth.ClassBreak; t {
			msg := xeth.Parse(buf)
			...
			xeth.Pool(msg)
		}
	}
}
...
goes.WG.Add(1)
go func() {
	defer goes.WG.Done()
	for {
		select {
