Found during the audit's docs pass. Wireshark's manuf file is tab-separated: prefix, a short name of at most 12 characters, then the full name. The generator split on any whitespace and glued both names together, so makers that only manuf lists showed as "IntegratedTe Integrated Technical Vision Ltd".

  • scripts/generate-oui.rs keeps the full name, and the short one only when it is the whole entry. A test fails on the old parser.
  • crates/netscli-core/data/oui.min.json.gz is regenerated from today's IEEE and Wireshark lists: 40,543 prefixes, up from 38,849.

Checked: cargo test in scripts/ passes, netscli-core oui tests pass, and spot checks show 0A:35:F2 = Integrated Technical Vision Ltd and 0A:2A:33 = Digistor.

…both names

manuf is tab-separated: prefix, a short name of at most 12 characters,
then the full name. The parser split on any whitespace and joined
everything after the prefix, so entries that only manuf supplies shipped
with the short name glued to the front of the full one, for example
"IntegratedTe Integrated Technical Vision Ltd". Take the full name, and
the short one only when it is the whole entry. Older files put the full
name in a trailing `#` comment, which is handled too.

The shipped dataset still has the glued names until the generator is run
again, which downloads the IEEE and Wireshark lists.
40,543 prefixes (was 38,849). Entries only Wireshark's manuf supplies now
carry one name, for example 0A:35:F2 is "Integrated Technical Vision Ltd"
instead of "IntegratedTe Integrated Technical Vision Ltd".
