Hello all,

The following series introduces RDMA read support and capabilities
reporting to the EFA driver.

RDMA read support, maximum transfer size and max SGEs per RDMA WR are
now being reported to the userspace library through the query device
verb.
In addition, remote read access is supported by the register MR verb.

PR was sent:
https://github.com/linux-rdma/rdma-core/pull/613

Changelog -
v1->v2: https://lore.kernel.org/linux-rdma/20191112091737.40204-1-galpress@amazon.com/
* Use max_sge_rd field in ib_device_attr struct instead of duplicating
  it in vendor specific ABI.

Thanks,
Gal
