Functions

func CalculateIPv4Checksum

func CalculateIPv4Checksum(bytes []byte) uint16

CalculateIPv4Checksum calculates the IPv4 checksum for the given bytes. copied from gopacket/layers/ip4.go because they didn't export one. for whatever some reason..

func UpdateIPv4Checksum

func UpdateIPv4Checksum(ip *layers.IPv4)

UpdateIPv4Checksum updates the IPv4 checksum field and the raw bytes for a gopacket IPv4 layer.

func UpdateTCPChecksum

func UpdateTCPChecksum(tcp *layers.TCP)

UpdateTCPChecksum updates the TCP checksum field and the raw bytes for a gopacket TCP layer.
