4. The FRMR api need to set key of MR through IB_WR_REG_MR.
But it is impossible to change a key of mr using uverbs.
FRMR is more like memory windows in user space, you can't support it
using just regular MRs.
It is hard to support this using uverbs, but it is easy to support
with uRDMA that we can get full control of mrs.
What is uRDMA?
Thanks
