====================
qed*: Improve performance on 100G link for offload protocols

This patch series modifies the current implementation of PF selection.
The refactoring of the llh code enables setting additional filters
(mac / protocol) per PF, and improves performance for offload protocols
(RoCE, iWARP, iSCSI, fcoe) on 100G link (was capped at 90G per single
PF).

Improved performance on 100G link is achieved by configuring engine
affinty to each PF.
The engine affinity is read from the Management FW and hw is configured accordingly.
A new hw resource called PPFID is exposed and an API is introduced to utilize
it. This additional resource enables setting the affinity of a PF and providing
more classification rules per PF.
qedr,qedi,qedf are also modified as part of the series. Without the
changes functionality is broken.

v1 --> v2
---------
- Remove iWARP module parameter. Instead use devlink param infrastructure
  for setting the iwarp_cmt mode. Additional patch added to the series for
  adding the devlink support.

- Fix kbuild test robot warning on qed_llh_filter initialization.

- Remove comments inside function calls
