Accidentally got an older version of the patch. This is the latest version.

sys/dev/ntb/ntb_hw/ntb_hw.c
2646 ↗	(On Diff #16491)	Should these be #defines that correspond with admin_up's states?

sys/dev/ntb/ntb_hw/ntb_hw.c
2646 ↗	(On Diff #16491)	NTB_SPEED/WIDTH are already a set of enums. For now, I don't think there's any need to expose speed/width as administrative configuration options. The hw will just train whatever the best it can sustain. Later, knobs could be added to configure speed/width like ifconfig.
