Poul-Henning Kamp eba2a1aeb9 |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). Submitted by: se Reviewed by: phk		2000-01-15 19:46:12 +00:00
