A simple OVS flow executor supporting `Go1.18+`.

## Example

```go

package main

import (

	"context"

	"github.com/xgfone/go-exec"

	"github.com/xgfone/go-ovs"

)

func main() {

	initBridge("br-ovs")

	initFlows("br-ovs")

}

func must(err error) {

	if err != nil {

		panic(err)

	}

}

func initBridge(bridge string) {

	must(exec.Execute(context.Background(),

		"ovs-vsctl", "--may-exist", "add-br", bridge,

		"--", "set-fail-mode", bridge, "secure",

	))

	must(exec.Execute(context.Background(),

		"ip", "link", "set", bridge, "up",

	))

}

func initFlows(bridge string) {

	// Table 0

	ovs.MustAddFlow(bridge, "table=0,in_port=1,actions=goto_table:1")

	ovs.MustAddFlow(bridge, "table=0,in_port=2,actions=goto_table:2")

	ovs.MustAddFlow(bridge, "table=0,in_port=3,actions=goto_table:3")

	ovs.MustAddFlow(bridge, "table=0,in_port=4,actions=goto_table:4")

	ovs.MustAddFlow(bridge, "table=0,priority=0,actions=drop")

	// TODO ...

}
