Startup timing out when there are hundreds of network interfaces

I have had two end-user issues now with lldpad timing out, on startup, because there are hundreds of network interfaces, and the code is trying to check them all.

In both cases, most of the network interfaces were for VMs and were not needed for DCB.

Is there any way to mask off the interfaces we don't want to check, in order to keep the startup time down? Or any other way to either avoid these copious interfaces, or at least not time out waiting for them to be checked?

Before I started looking at how to add a "mask" I thought I'd ask.
