Somewhat separate from this specific patch, this is my concern.

There are continual requests to modify the kernel verbs interfaces.  These 
requests boil down to exposing proprietary capabilities to the latest version 
of some vendor's hardware.  In turn, these hardware specific knobs bleed into 
the kernel clients.

At the very least, it seems that there should be some sort of discussion if 
this is a desirable property of the kernel verbs interface, and if this is the 
architecture that the kernel should continue to pursue.  Or, is there an 
alternative way of providing the same ability of coding ULPs to specific HW 
features, versus plugging every new feature into 'post send'?
