ipfw sched show output mangled (PR/bug 210882)

[Guido Falsi]

Hi,

I have filed the PR in the subject [1], I'd like to ask if someone could
have a look, it's a bug I noticed on head which is also going to affect
11.0 if not corrected in time.

Since r270424, the output of certain ipfw show commands is mangled, due
to buffers not being cleaned between uses. The PR contains an example of
mangled "ipfw sched show" command.

The PR has two patches which together restore the output as it used to
be before r270424.

Is there someone available to review and commit it to the tree?

Thanks in adance!
