IB/core: generic RDMA READ/WRITE API2016-05-13T17:37:19ZChristoph Hellwighch@lst.de2016-05-03T16:01:09Zurn:sha1:a060b5629ab066dd1d321430eeb96f70939a1790
This supports both manual mapping of lots of SGEs, as well as using MRs
from the QP's MR pool, for iWarp or other cases where it's more optimal.
For now, MRs are only used for iWARP transports. The user of the RDMA-RW
API must allocate the QP MR pool as well as size the SQ accordingly.
Thanks to Steve Wise for testing, fixing and rewriting the iWarp support,
and to Sagi Grimberg for ideas, reviews and fixes.
