[collectd] [PATCH] Interface option for network plugin

[Max Henkel]

Dear collectd-developers, users and fans!

Please excuse my possible double-post, but I've just found out that
the email was sent in a similar way as Fabian Linzbergers one in
July 2009. Thus I'm expecting that it also got lost at least in some
of your mailboxes.

I'm very impressed by the features and the idea of collectd.
It's very useful for the operation on embedded devices like the
OpenWRT-supported ones, because of its efficient operation and the
small memory footprint. During my tests I've considered the following
as a nice improvement.

The default behaviour of collectd to let the kernel choose the
default outgoing/incoming interface for multicast traffic is not
always a good choice, since the Linux kernel let's you only specify
one default route for multicast traffic or the system has to be
configured as a multicast router (which can be an overkill). To have
the opportunity to express the desired interface explicitly I've
created a patch against the current master.

The patch tries to follow the coding standard, the idea of the
configuration file and the structure of the network plugin as close
as possible. Furthermore I've tried to accomplish it with
interoperability in mind. Nonetheless there might be some (many ;-)
unconsidered issues from my side and thus:

  Suggestions and feedback is _greatly_ appreciated. :-)

Maybe it will help somebody or it gets collect(e)d for inclusion ;-)

Thank you for this nice piece of software!

Best regards,

Max
