My understanding is that scripts in /if-up.d/ get run every time any interface
is brought up. So if you're bringing up 2 interfaces, it will get run twice.
It looks like a number of environment variables are set before the script
is run, so you can check inside the script which interface is being brought
up and respond accordingly. I.e, exit if it's not eth0 or whatever. I can
see a number of scripts in there on my system that do things like:

if [ "$IFACE" != lo ]; then
    blah blah blah
fi
