Hello net@ folks, I came across some performance problems with BPF on 10G links, and have been investigating more on this. The first thing I noticed is that, bpf_if structures are protected with a mutex. I was wondering if that has been done for a special purpose, i.e. rmlocks are not allowed to run in interrupt context or so? -- Murat
