See https://github.com/golang/net/blob/master/ipv4/header.go#L109 for an example. Note that https://golang.org/pkg/encoding/binary/ only support big endian and little endian, but not native endian. This blog post may be useful: https://commandcenter.blogspot.com/2012/04/byte-order-fallacy.html If you need to support bad written protocols using native endian, see https://github.com/golang/net/blob/master/internal/socket/sys.go.
