[Selvin Xavier <selvin.xavier@broadcom.com>]

This series introduces the RoCE driver for the Broadcom
NetXtreme-E 10/25/40/50G RoCE HCAs.
This driver is dependent on the bnxt_en NIC driver and is
based on the for-4.11 branch in linux-rdma repository.
bnxt_en changes required for this patch series are already
available afore mentioned branch.

These changes are available for your reference in
the bnxt_re_v5 branch of following repository.

Doug,
This patchset addresses review comments from you and Leon.
This series also includes some changes required for the latest FW.
Please consider applying this to linux-rdma tree.

Thanks,
Selvin Xavier

v4->v5:
  * Removes rdev ref_count as this is not necessary. 
  * Adds a check to see if the device is supporting RoCE
  * Updating the PF FW communication channel offset as per
    the latest FW changes
  * Use min_t macro to calculate the number CQ and QP entries
  * Adds ib_udata parameter to create_ah verb
  * Uses ETH_P_IBOE macro for RoCE ethertype
  * Code refactoring based on the review comments from Leon

v3->v4:
  * Changes driver folder name to bnxt_re and remove the bnxt_re/bnxt
    prefix from the individual files inside the driver folder.
  * Changes the file name bnxtre-abi to bnxt_re-abi.h to align with
    convention <module_name>-abi.h
  * Updates the Makefile and Kconfig file with new format change.

v2->v3:
  * Fix 0day build breakage
  * Fix cocci, kbuild robot, sparse, smatch and checkpatch warnings
  * Changed the filename bnxt_re_uverbs_abi.h  to bnxtre-abi.h
  * Removed the __packed qualifier from the uverbs structure and adjusted
    the structure alignment to 64bits.
  * Added retry count to bail out in case of delayed or no response
    to FW commands
  * Removed the debugfs support from this patch series
  * Changed some of the defines as inline functions based on Jason's comment
  * Split two functions to get rid of switch within switch construct
  * Removed bnxt_re_copy_to_udata as it is just a wrapper for ib_copy_to_udata
  * Added maintainers information to MAINTAINERS file

v1-> v2:
  * The license text in each file updated to reflect Dual license.
  * Makefile and Kconfig changes are pushed to the last patch
  * Moved bnxt_re_uverbs_abi.h to include/uapi/rdma folder
  * Remove duplicate structure definitions from bnxt_re_hsi.h as
    it is available in the corresponding bnxt_en header file (bnxt_hsi.h)
  * Removed some unused code reported during code review.
  * Fixed few sparse warnings
