Seth Hall updated BIT-553:

    Resolution: Feedback Missing
        Status: Closed  (was: Open)

I don't think we're going to bother with this especially since packet capture might get overhauled a bit soon.

> Newer pcap versions have a pcap_set_buffer_size(). This call can be used to adjust the kernel level buffer size for captures. (E.g., Linux PF_RING's buffer size, which will be quite important if we start using 64KB snaplen)
> It's supported for all platforms we care about (Linux, BPF-based OSes), but we probably want to make sure that it obsoletes the manual tuning through:

> (It might well be that one still has to manually increase the max buffer sizes)
