Support added to staqfq for sfq, enhanced sfq, and sfq + red

The increasingly misnamed staqfq script now does qfq, sfq,
eric's enhanced sfq, and sfqred to some extent, for both
wired and wireless.

And is getting messier and messier by the second.

Desparately needs conf file and argv support, a usage
function, a man page, and a new name.

Further thought is required on how to correctly configure
these for different bandwidths, and configure HTB correctly,
and configure TSO/GSO correctly.

Also:

* Fixed multiqueue checking
* Fixed vlan check
* Increased QFQ bins to 2048
* Lowered default MAX_HWQ_BYTES to 3000
* Deleted FORCE_100Mbit option
* Added FORCE_SPEED option to force a wire speed
* Added FORCE_RING option to force a tx ring size
* Added (some) mqprio support
