  Log:
  |The hard limit for the BPF buffer size is 32KB, which appears too low
  |for high speed networks (even at 100Mbit/s this corresponds to 1/300th
  |of a second). The default buffer size is 4KB, but libpcap and ipfilter
  |both override this (using the BIOCSBLEN ioctl) and allocate 32KB.
  |
  |The following patch adds an sysctl for bpf_maxbufsize, similar to the
  |one for bpf_bufsize that you added back in December 1995. I choose to
  |make the default for this limit 512KB (the value suggested by NFR).
