Can this flushing be somehow done with the current librdmacm/libibverbs APIs
or we need some enhancement?

You can call verbs directly to transition the QP state.  That leaves the CM state unchanged, which doesn't really matter for UD QPs anyway.

Alex,

Any reason we can't deploy this hack? is that for the IPoIB port space 
it would
require copying some low level code from librdmacm or even from the 
kernel? e.g
the IPoIB qkey, etc.

Or.
