luci-mod-network: fill ieee-oui.txt from ufp-neigh

[ckorber]

With ufp-neigh it is possible to get the vendor of a MAC address. Because arp-scan allows us to specify a txt file for lookup, it is suitable to use ufp-neigh to create a txt file on the spot and populate it with vendors of connected devices. This is only used if ufp is running as service.

Depends on changes to ufp.

Sorry, my bad. Forgot about it.

I can't find a repo for it, so it's a bit of a shame we can't make a PR for it.

Reviewed the diff at c7397db. One inline comment on load() error handling. The ufp-side fingerprint/export ubus interface this depends on is not yet merged and has no public repo (already discussed in-thread), so the backend coupling can't be verified here; that blocker is correctly noted in the PR description.

Reviewed 1 new commit; no new issues found. The load() chain is now wrapped in L.resolveDefault(..., null), which resolves the prior comment about a rejected fingerprint call breaking the whole diagnostics page.
