linux-next: build failure after merge of the rdma tree

Hi Doug,

After merging the rdma tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/infiniband/hw/bnxt_re/main.c: In function 'bnxt_re_net_ring_free':
drivers/infiniband/hw/bnxt_re/main.c:231:18: error: 'RING_ALLOC_REQ_RING_TYPE_CMPL' undeclared (first use in this function)
  req.ring_type = RING_ALLOC_REQ_RING_TYPE_CMPL;
                  ^
drivers/infiniband/hw/bnxt_re/main.c:231:18: note: each undeclared identifier is reported only once for each function it appears in
drivers/infiniband/hw/bnxt_re/main.c: In function 'bnxt_re_net_ring_alloc':
drivers/infiniband/hw/bnxt_re/main.c:271:18: error: 'RING_ALLOC_REQ_RING_TYPE_CMPL' undeclared (first use in this function)
  req.ring_type = RING_ALLOC_REQ_RING_TYPE_CMPL;
                  ^

Caused by commit

  1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")

interacting with commit

  bac9a7e0f5d6 ("bnxt_en: Update to firmware interface spec 1.7.0.")

from the net-next tree.

I added this merge fix patch:

Thanks Stephen.  I had been forewarned about this by Selvin and I
instructed him to send me a fixup patch that would resolve the issue.  I
would apply it to my tree before merging with Linus.  He just hadn't
time to send it yet.  Your patch is sufficient as well, so I may just
pull it in.  Thanks again.
