pfSense

So there's code for this MAC -> manufacturer mapping in multiple places introduced by https://github.com/pfsense/pfsense/commit/57f2840e1faacf50b1a93d7954bb576eca77475b but it's no-op unless people install nmap package, because it relies on /usr/local/share/nmap/nmap-mac-prefixes

Then there's a fugly hack in nmap package which checks whether the file exists or not (for god knows what reason) and symlinks it if it doesn't - https://github.com/pfsense/pfsense-packages/blob/master/config/nmap/nmap.inc#L33

Can we ship the file with pfSense itself instead in a location that doesn't conflict with nmap package? The nmap file is outdated anyway, updated can be either scripted (e.g. http://giantdorks.org/alain/script-to-update-nmap-mac-prefixes-with-latest-entries-from-the-ieee-oui-database/) or the up-to-date sanitized data fetched from http://linuxnet.ca/ieee/oui/ (direct URL: http://linuxnet.ca/ieee/oui/nmap-mac-prefixes)
