We want to use tcpdump filter functionality on a DSA/EDSA link layer device, but there doesn't seem to be supported right now. I'm not well versed in the libpcap implementation so I naively looked at the existing code and did the following changes in this PR. Please don't hit me over the head :/
Is this the right way of doing it or do you have any suggestions where I should look for a better solution/approach?
Best regards,
