more tests - pf + altq + cbq(borrow) not borrowing from parent

[Peter]

Did more testing:

Downloading on workstation from server / Server uploading.
I'm dealing only with fxp0, and only one IP and only ssh/sftp running.

uploads +/- several KB as they vary during the 1 minute test [100MB tgz file]

In theory and example as seen on
http://www.openbsd.org/faq/pf/queueing.html - Example #2: Company Network

 The poshta queue should borrow fully from the parent queue [extranet],
but borrowing seems to _only_ work from the root queue/first level down.

Am I missing something here?
