Re: [PATCH 1/2] libibverbs: Allow 3rd party extensions to verb routines

These additions would include the new ibv_cmd_xxx functions

I believe the only case where using an extension would make sense if
it if can be implemented entirely within the low level driver. So you
can't add new ibv_cmd calls to ibverbs, must duplicate them in your
driver, etc.

I'm a little unclear on how the application is going to get the access
enums and other structure definitions, though.. I suppose the low
level driver can install a .h file as well.
 

Each new third-party package would need such a library.  While this
will lead to a multiplicity of new libraries (one per addition), the
core libibverbs package would remain as is.

I definitely don't want to see this..
