The EtherTap object is going to be reworked so that it connects to a tap device directly, but it's worthwhile to still be able to use the m5tap utility (util/tap) to send/receive packets on systems which don't support tap but do support the pcap API. It can also be used to replay ethernet frames, to capture the ethernet frames coming from gem5 for analysis, to programmatically consume and/or generate the frames, or even to forward them to/from a remote system.
