The article mentions the servers run up to 100 different BPF related programs on an individual server. I get the firewall and traffic shaping stuff, but are there any unusual use-cases or hacks you could share?

We talked about it back in 2014 when it did not use BPF https://tracingsummit.org/w/images/6/6f/TracingSummit2014-Tr...
