Package gorandpacket is a go library for randomly generating ethernet packets It's main purpose is for testing networking software/hardware

Usage

type RandPacketT

type RandPacketT struct {
	MACLen int
	Seed   int64
	Rand   *rand.Rand
}

Struct RandPacket holds the gorandpacket object

func NewGorandPacket

func NewGorandPacket() RandPacketT

NewGorandPacket Factory method for gorandpacket

func (*RandPacketT) RandByte

func (r *RandPacketT) RandByte() byte

RandByte Generate a random byte
