====================
qed: RocE & iSCSI infrastructure

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.
