Subject: [PATCH v4 net-next 0/7] qed*: RDMA and infrastructure for iWARP

This series focuses on RDMA in general with emphasis on required changes
toward adding iWARP support. The vast majority of the changes introduced
are in qed/qede, with a couple of small changes to qedr
[mentioned below].

The infrastructure changes:
 - Patch #1 adds the ability to pass PBL memory externally for a newly
created chain.
 - Patches #4, #5 rename qede_roce.[ch] into qede_rdma.[ch] + change
prefixes from _roce_ to _rdma_, as the API between qede and qedr is
agnostic to the variant of the RDMA protocol used. These patches also
touch qedr [basically to align it with the renaming, nothing more].
 - Patch #7 replaces the current SPQ async mechanism into serving
registered callbacks [before adding iWARP which would add another client
in need of this sort of functionallity].

The non-infrastrucutre changes:
 - Patches #2, #3 contain DCB-related changes to better align RDMA with
configured DCB.
 - Patch #6 contains a minor [mostly theoretical fix] to release flow.

Dave,

Please consider applying this series to `net-next'.

Thanks,
Yuval

Changes from previous versions
------------------------------
 - V4: This is actually a repost of V3 due to some confusion regarding
   the sent cover-letter
 - V3: Add commit log message in #4 indicating change in header inclusion
 - V2: Add several inclusion into qede_rdma.h to have proper declarations
   of all variable types used in it

Michal Kalderon (3):
  qed*: qede_roce.[ch] -> qede_rdma.[ch]
  qed*: Set rdma generic functions prefix
  qed: Wait for resources before FUNC_CLOSE
  qed: SPQ async callback registration

Yuval Mintz (4):
  qed: Chain support for external PBL
  qed: RoCE EDPM to honor PFC
  qed: Disable RoCE dpm when DCBx change occurs
