I've added a comment.

Yes, but as that enum is used only to control how the item is formatted,
you don't want to distinguish between them in that case.  It's
sufficient to give each one its own entry in
"radius_vendor_3gpp_attrib".  (Ultimately, as much as possible of the
stuff in packet-radius.c should probably come from a file read at
startup time, rather than requiring packet-radius.c to be changed in
order for it to know about new attributes.

I made the ones that are IP addresses use type RADIUS_IP_ADDRESS.

I've added a RADIUS_IP6_ADDRESS type and used that for the IPv6 address
attributes.

TS 29.061 V5.7.0 says "Charging ID value: 32 bits unsigned integer".  I
made it RADIUS_INTEGER4.

Checked in, with the aforementioned changes.
