Documentation for meaning of each ipset type component missing

[dead-claudia]

I've inferred from https://github.com/firewalld/firewalld/blob/master/src/firewall/core/io/ipset.py that each component of the type attribute of <ipset>s means the following:

• ip: IP address
• net: IP address, IP range, or subnet mask
• mac: MAC address
• port: either a local port or protocol:port pair with the following named protocols supported: icmp, icmpv6/ipv6-icmp, tcp, udp, udplite, and sctp (it doesn't actually delegate to /etc/protocols for textual shorthands)
• mark: a 32-bit integer mark as documented in https://firewalld.org/documentation/man-pages/firewalld.richlanguage.html
• iface: network interface (say, eth0 or enp0s3)

None of this appears properly documented anywhere, either in the man page or the website. Could this be corrected?
