-// BUG(mikio): On every POSIX platform, reads from the "ip4" network
-// using the ReadFrom or ReadFromIP method might not return a complete
-// IPv4 packet, including its header, even if there is space
-// available. This can occur even in cases where Read or ReadMsgIP
-// could return a complete packet. For this reason, it is recommended
-// that you do not uses these methods if it is important to receive a
-// full packet.
-//
-// The Go 1 compatibility guidelines make it impossible for us to
-// change the behavior of these methods; use Read or ReadMsgIP
-// instead.
