We plan on sending 2 new protocol drivers in the imminent future -
both our RoCE [qedr] and iSCSI [qedi] drivers. As both submissions
would be rather massive and in order to avoid collisions between them,
the common infrastructure on the qed side was prepared as an independent
patch-series to be sent ahead of those 2 submissions.

This patch series introduces in QED 2 new 'ids' - one for iscsi and
one for roce. It then goes and adds logic required for configuring
said protocols in HW. Notice it *doesn't* actually add any client using
said ids, but rather only the infrastructure to allow their later usage.

What this patch doesn't contain is the slowpath protocol-configuration
toward the firmware. I.e., it contains register-setting logic, memory
allocations, etc., but not actual flow-related configuration specific
to the protocl. Those would be sent as part of the protocol driver
submissions.

Dave,

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

Thanks,
Yuval

RoCE driver is going to need a 32-bit chain [current chain implementation
for qed* currently supports only 16-bit producer/consumer chains].

This patch adds said support, as well as doing other slight tweaks and
modifications to qed's chain API.

From: Yuval Mintz @ 2016-06-03 11:35 UTC (permalink / raw)
  To: davem, netdev; +Cc: Rajesh.Borundia, shyam.sundar, Yuval Mintz

This adds the qed portion of the RoCE & iSCSI firmware HSI,
as well as adding several new common HSI files which would be required
by both qed and qed* protocols.

  To: davem, netdev; +Cc: Rajesh.Borundia, shyam.sundar, Yuval Mintz

RoCE and iSCSI would require some added/changed hw configuration in order
to properly run; The biggest single change being the requirement of
allocating and mapping host memory for several HW blocks that aren't being
used by qede [SRC, QM, TM, etc.].

In addition, whereas qede is only using context memory for HW blocks, the
new protocol would also require task memories to be added.
