This patch series used the doorbell overflow recovery mechanism
introduced in
commit 36907cd5cd72 ("qed: Add doorbell overflow recovery mechanism")
for rdma ( RoCE and iWARP )
rdma-core pull request #493
Changes from V2:
- Don't use long-lived kmap. Instead use user-trigger mmap for the
doorbell recovery entries.
- Modify dpi_addr to be denoted with __iomem and avoid redundant
casts
Changes from V1:
- call kmap to map virtual address into kernel space
- modify db_rec_delete to be void
- remove some cpu_to_le16 that were added to previous patch which are
correct but not related to the overflow recovery mechanism. Will be
submitted as part of a different patch
