[ixpmanager] update-l2database.pl not updating database

[Brian Thompson]

Nick,

Could we have a new switch port type e.g. "core-other" that could define
the edge of sflow data, so the data is collected and counted from all
non-sflow peers as an aggregate.   We very much would like to have the
sflow data for the other members of the exchange.

Thanks
Brian
