PAUSE frames are specified to be minimum-length Ethernet frames, i.e.,
46 bytes in the Data field. The Data field must be padded to this length.
If the frame was shorter than 64 bytes overall (i.e., less than 46 bytes
of Data), it would be discarded by any compliant Ethernet receiver, and
thus would not be of much use.
