Number of queues possible
ALTQ algorithm for PRIQ has a forced 15 queue limitation.
While the other algorithms are forced to a 4096 queue limit build time limit.
Triggered by http://forum.pfsense.org/index.php/topic,34435.0.html it would be nice to have the GUI spit out a nice error message when limit reached or remove the limit at all if possible.

PRIQ also doesn't allow the use of the same priority for more than one queue:
pfctl: q3 does not have a unique priority on interface vtnet0 /tmp/rules.debug:50: errors in queue definition
#define PRIQ_MAXPRI 16 /* upper limit of the number of priorities */
