luigi 20a6693414 close pr 10889:
+ add a missing call to dn_rule_delete() when flushing firewall
  rules, thus preventing possible panics due to dangling pointers
  (this was already done for single rule deletes).
+ improve "usage" output in ipfw(8)
+ add a few checks to ipfw pipe parameters and make it a bit more
  tolerant of common mistakes (such as specifying kbit instead of Kbit)
