EtherCat is a networking utility in the style of netcat for reading and writing to raw ethernet sockets on Linux.
cargo build
ethercat <your_ethernet_interface> <dest_mac_address>
Note: You may have to add sudo to this command in order to get permission to create raw ethernet sockets. Wireshark and other tools work around this restriction by creating a packet-capturing user group, but this whole group has root-level permissions, so this approach can be dangerous on production machines.
cat README.md | sudo ethercat enp0s31f6 00:00:00:00:00:00
On my development machine, I have an ethernet port under the name enp0s31f6. If you have a live ethernet port (and sudo permissions!) you can see packets appear in Wireshark or other packet monitoring tools.
