67b40dccc4 qed: Implement iWARP initialization, teardown and qp operations
This patch adds iWARP support for flows that have common code
between RoCE and iWARP, such as initialization, teardown and
qp setup verbs: create, destroy, modify, query.
It introduces the iWARP specific files qed_iwarp.[ch] and
iwarp_common.h

b71b9afdf6 qed: Split rdma content between qed_rdma and qed_roce
This patch places common iWARP / RoCE code in qed_rdma
and roce specific code in qed_roce

There is one new function ( qed_roce_setup ) added, the rest
of the patch removes content from the files and removes some
static definitions.

1d6cff4fca qed: Add iSCSI out of order packet handling.
This patch adds out of order packet handling for hardware offloaded
iSCSI. Out of order packet handling requires driver buffer allocation

0189efb8f4 qed*: Fix Kconfig dependencies with INFINIBAND_QEDR
The qedr driver would require a tristate Kconfig option [to allow
it to compile as a module], and toward that end we've added the
INFINIBAND_QEDR option. But as we've made the compilation of the
qed/qede infrastructure required for RoCE dependent on the option
we'd be facing linking difficulties in case that QED=y or QEDE=y,
and INFINIBAND_QEDR=m.

To resolve this, we seperate between the INFINIBAND_QEDR option
and the infrastructure support in qed/qede by introducing a new
QED_RDMA option which would be selected by INFINIBAND_QEDR but would
be a boolean instead of a tristate; Following that, the qed/qede is
fixed based on this new option so that all config combinations would
be supported.

39651abd28 qed: add support for dcbx.
This patch adds the necessary driver support for Management Firmware to
configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

1408cc1fa4 qed: Introduce VFs
This adds the qed VFs for the first time -
The vfs are limited functions, with a very different PCI bar structure
[when compared with PFs] to better impose the related security demands
associated with them.

This patch includes the logic neccesary to allow VFs to successfully probe
[without actually adding the ability to enable iov].
This includes diverging all the flows that would occur as part of the pci
probe of the driver, preventing VF from accessing registers/memories it
can't and instead utilize the VF->PF channel to query the PF for needed
information.

Add support for a new Kconfig option for qed* driver which would allow
[eventually] the support in VFs.

This patch adds the necessary logic in the PF to learn about the possible
VFs it will have to support [Based on PCI configuration space and HW],
and prepare a database with an entry per-VF as infrastructure for future
interaction with said VFs.

25c089d78f qed: Add basic L2 interface
This patch adds a public API for a network driver to work on top of QED.
The interface itself is very minimal - it's mostly infrastructure, as the
only content it has after this patch is a query for HW-based information
required for the creation of a network interface [I.e., no actual
protocol-specific configurations are supported].

fe56b9e6a8 qed: Add module with basic common support
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
products by Qlogic.

This module serves two main purposes:
 1. It's responsible to contain all the common code that will be shared
    between the various drivers that would be used with said line of
    products. Flows such as chip initialization and de-initialization
    fall under this category.

 2. It would abstract the protocol-specific HW & FW components, allowing
    the protocol drivers to have a clean APIs which is detached in its
    slowpath configuration from the actual HSI.

This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.
