By "things" do you mean protocol filterable fields (in which case see
Ronnie Sahlberg's reply) or do you mean "values stored directly in the
packet_info structure"?  If the latter, then there is a complete list -
which is a list of the fields in a "packet_info" structure, so you've
already found the list.  (For example, the link-layer source and
destination addresses are in "dl_src" and "dl_dst", the network-layer
source and destination addresses are in "net_src" and "net_dst", and
"src" and "dst" contain the network-layer addresses if there are any,
otherwise the link-layer addresses.)
