[ofa-general] Fast Reg Question

[Tom Tucker]

Roland:

I'm a little perplexed by the fast reg WR definition. The context is 
that I'm using the Fast Reg verb to map the local memory that is the 
data source for an RDMA_WRITE.

The WR format, however, only takes an rkey. How does this all work when 
you're using fast reg to map local memory? Does the WR really need the 
mr pointer, or both the lkey and rkey? The IBTA spec seems to indicate 
that it needs more information about the MR than just the rkey.
