--==_Exmh_417521302P Content-Type: text/plain; charset=us-ascii Hi -net folk... Awhile back, I was trying to figure out how bridge(4) worked, but discovered that the manpage didn't list all the sysctls necessary to configure the bridge. I filed a PR (22060) asking someone to look into this. I subsequently lost interest in bridge(4), but gained a commit bit, the result being that I own a PR for something I know close to zero about. I've made the following diff against the bridge.4 manpage in -CURRENT. Can someone tell me if this is anywhere close to the state of reality? Thanks for any assistance! Bruce.
