536f092805 RDMA/bnxt_re: Specify RDMA component when allocating stats context
Starting FW version 20.6.47, firmware is keeping separate statistics
for L2 and RDMA. However, driver needs to specify RDMA or not when
allocating stat_ctx.

ac1820fb28 Merge tag 'for-next-dma_ops' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma DMA mapping updates from Doug Ledford:
 "Drop IB DMA mapping code and use core DMA code instead.

  Bart Van Assche noted that the ib DMA mapping code was significantly
  similar enough to the core DMA mapping code that with a few changes it
  was possible to remove the IB DMA mapping code entirely and switch the
  RDMA stack to use the core DMA mapping code.

  This resulted in a nice set of cleanups, but touched the entire tree
  and has been kept separate for that reason."

db690328a7 RDMA/bnxt_re: fix for "bnxt_en: Update to firmware interface spec 1.7.0."
When the firmware interface spec was updated, a constant element was
renamed.  The rename missed the instances in the bnxt_re driver
because it wasn't upstream yet.  This updates the bnxt_re driver
with the rename.

1ac5a40479 RDMA/bnxt_re: Add bnxt_re RoCE driver
This patch introduces the RoCE driver for the Broadcom
NetXtreme-E 10/25/40/50G RoCE HCAs.

The RoCE driver is a two part driver that relies on the parent
bnxt_en NIC driver to operate.  The changes needed in the bnxt_en
driver have already been incorporated via Dave Miller's net tree
into the mainline kernel.

The vendor official git repository for this driver is available
on github as:
