How the 24 bit wide MR keys can handle INT_MAX unique
MR's?
Not sure if I understand this correctly, lkey and rkey are u32 in ib_mr.
The upper 8 bits of an ib_mr remote token are reserved for use as a
rotating key, this allows a consumer to more safely reuse an ib_mr
without having to overallocate large region pools.
