[shurd]

Summary

Initial cut of an iflib(4) manpage. For now, just a place
to document tunable and statistic sysctls.

[shurd]

Remove iflib.c patch.

I wish there was a previewer for these...

Can you run textproc/igor for the line breaks in the man page and possibly other errors? mandoc -Tlint would also be great.

Thanks!

share/man/man4/iflib.4

There needs to be a line break after a sentence stop.

88

Another line break is needed here after the sentence stop.

90

Another line break here...

109

Line break is needed here after the sentence stop.

Run through igor and mandoc -Tlint

I still get a style warning, presumably because the prefix ends with a
period.

mandoc: man4/iflib.4:27:18: STYLE: no blank before trailing delimiter: Va dev.X.Y.iflib.

I think that's fine in this case. Thanks for the updates.
