As mentioned in #24984, I'm making another issue to document the address format for AF_PACKET. In this case there's already documentation in Modules/socketmodule.c that says:
- an AF_PACKET socket address is a tuple containing a string
 specifying the ethernet interface and an integer specifying
 the Ethernet protocol number to be received. For example:
 ("eth0",0x1234). Optional 3rd,4th,5th elements in the tuple
 specify packet-type and ha-type/addr.
But nothing has been added to Doc/library/socket.rst .
The documentation needs to be confirmed with the code. (It probably should be altered somewhat to state how you "specify packet-type and ha-type/addr"... and maybe what a "ha-type/addr" is... A quick Google search found this very useful reference: https://books.google.ca/books?id=Chr1NDlUcI8C&pg=PA472&ots=OCEwyjdXJo&sig=PuNG72WIvv4-A924f9MvzPtgQDc&hl=en&sa=X&ved=0CE8Q6AEwCGoVChMI6IiTyoDqxwIVCTs-Ch3bCAXy#v=onepage&q&f=false )
