Is this code going to get invoked very often?

In practice, it would be invoked when matching any listen requests originating 
from the CMA (RDMA connection abstraction).

If so, can the mask operation use a "native" size since
IB_CM_PRIVATE_DATA_COMPARE_SIZE is hard coded to 64 byte?

e.g something like:
	for (i = 0; i < IB_CM_PRIVATE_DATA_COMPARE_SIZE/sizeof(unsigned long);
									i++)
		((unsigned long *)dst)[i] = ((unsigned long *)src)[i] 
						& ((unsigned long *)mask)[i];

Yes - something like this should work.  Thanks.
