Description
Currently, the vdev_knob default values (such as vq_max_pending) are hard coded.  Though they
can be changed (say via mdb), that's not an acceptable solution.

The one value that's popped up in discussions and on jurassic is vq_max_pending as its default
 value of 35 was modeled after a single disk.  If a pool is created with vdevs that represent
 more than one disk, this number doesn't make as much sense and can hurt performance.
