Ed Schouten 136600fe59 Change bpf(4) to use the cdevpriv API. ... Right now the bpf(4) driver uses the cloning API to generate /dev/bpf%u. When an application such as tcpdump needs a BPF, it opens /dev/bpf0, /dev/bpf1, etc. until it opens the first available device node. We used this approach, because our devfs implementation didn't allow per-descriptor data. Now that we can, make it use devfs_get_cdevpriv() to obtain the private data. To remain compatible with the existing implementation, add a symlink from /dev/bpf0 to /dev/bpf. I've already changed libpcap to compile with HAVE_CLONING_BPF, which makes it use /dev/bpf. There may be other applications in the base system (dhclient) that use the loop to obtain a valid bpf. Discussed on: src-committers Approved by: csjp		2008-08-13 15:41:21 +00:00
