netaddr should optionally use ieee data in /var/lib instead of /usr/share

[zebul666]

netaddr python package uses 2 files oui.txt and iab.txt to make mac address look up and others.

However, the files

/usr/lib/python2.7/dist-packages/netaddr/eui/iab.txt
/usr/lib/python2.7/dist-packages/netaddr/eui/oui.txt

are symlinks to, respectively,
/usr/share/ieee-data/iab.txt
/usr/share/ieee-data/oui.txt

from the package ieee-data.

But if you update the files with update-ieee-data, the updated files lies in /var/lib/ieee-data and not in /usr/share/ieee-data

So the python package will continue to use the old ones.

The fix is simple. Use symlink towards
/var/lib/ieee-data/iab.txt
/var/lib/ieee-data/oui.txt
respectively instead

But what I describe above is not enough. Because netaddr module use index files, generated from oui.txt and iab.txt

So you need also to update those index files otherwise the mac vendor look up will be broken.

So I created symlinks in /usr/lib/python2.7/dist-packages/netaddr/eui for oui.idx and iab.idx towards /var/lib/ieee-data/oui.idx and /var/lib/ieee-data/iab.idx respectivelly.

Then used that python script to regenerate the index files

from netaddr.eui import ieee
ouiidx = ieee.FileIndexer('oui.idx')
oui = ieee.OUIIndexParser('oui.txt')
oui.attach(ouiidx)
oui.parse()
oui.detach(ouiidx)

iabidx = ieee.FileIndexer('iab.idx')
iab = ieee.IABIndexParser('iab.txt')
iab.attach(iabidx)
iab.parse()
iab.detach(iabidx)

I don't know how you could manage this at the package level ? But this is really needed
