We would like to create Ethernet frames that carry various protocols, but would settle for just IP packets. It would require that the frames contained custom MAC addresses so we can simulate hundreds of sources and destinations.

s/tcpdump/ping and traceroute/. tcpdump uses libpcap. Actually, there
is a module - Net::RawIP - that has low level capabilities, but it's basically
read only, as it also uses libpcap. You can peek at incoming ether frames but
you can't build them.
You may end up better off using an existing C based tool such as
and modifying it to use random mac addrs. You would have better
performance than you would be able to coax from perl anyway.
