To activate RoCE/SRIOV, need to remove the following:
1. In mlx4_ib_add, need to remove the error return preventing
initialization of a RoCE port under SRIOV.
2. In update_vport_qp_params (in resource_tracker.c) need to remove
the error return when a RoCE RC or UD qp is detected.
This error return causes the INIT-to-RTR qp transition to fail
in the wrapper function under RoCE/SRIOV.

Since there is no connection between the MAC/VLAN and the GID
when using IP-based addressing, the proxy QP1 (running on the
slave) must pass the source-mac, destination-mac, and vlan_id
information separately from the GID. Additionally, the Host
must pass the remote source-mac and vlan_id back to the slave,
This is achieved as follows:
Outgoing MADs:
1. Source MAC: obtained from the CQ completion structure
(struct ib_wc, smac field).
2. Destination MAC: obtained from the tunnel header
3. vlan_id: obtained from the tunnel header.
Incoming MADs
1. The source (i.e., remote) MAC and vlan_id are passed in
the tunnel header to the proxy QP1.
VST mode support:
For outgoing MADs, the vlan_id obtained from the header is
discarded, and the vlan_id specified by the Hypervisor is used
instead.
For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the
"invalid" vlan (0xffff) is substituted when forwarding to the slave.

The IB side of RoCE requires the MAC table index of the
MAC address used by its QPs.
To obtain the real MAC index, the IB side registers the
MAC (increasing its ref count, and also returning the
real MAC index) during the modify-qp sequence.
This protects against the ETH side deleting or modifying
that MAC table entry while the QP is active.
Note that until the modify-qp command returns success,
the MAC and VLAN information only has "candidate" status.
If the modify-qp succeeds, the "candidate" info is promoted
to the operational MAC/VLAN info for the qp. If the modify fails,
the candidate MAC/VLAN is unregistered, and the old qp info
is preserved.
The patch is a bit complex, because there are multiple qp
transitions where the primary-path information may be
modified: INIT-to-RTR, and SQD-to-SQD.
Similarly for the alternate path information.
Therefore the code must handle cases where path information
has already been entered into the QP context by previous
qp transitions.
For the MAC address, the success logic is as follows:
1. If there was no previous MAC, simply move the candidate
MAC information to the operational information, and reset
the candidate MAC info.
2. If there was a previous MAC, unregister it. Then move
the MAC information from candidate to operational, and
reset the candidate info (as in 1. above).
The MAC address failure logic is the same for all cases:
- Unregister the candidate MAC, and reset the candidate MAC info.
For Vlan registration, the logic is similar.

The GIDs are statically distributed, as follows:
PF: gets 16 GIDs
VFs: Remaining GIDS are divided evenly between VFs activated by the driver.
If the division is not even, lower-numbered VFs get an extra GID.
For an IB interface, the number of gids per guest remains as before: one gid per guest.

For IB transport, the host determines the slave GIDs. For ETH (RoCE),
however, the slave's GID is determined by the IP address that the slave
itself assigns to the ETH device used by RoCE.
In this case, the slave must be able to write its GIDs to the HCA gid table
(at the GID indices that slave "owns").
This commit adds processing for the SET_PORT_GID_TABLE opcode modifier
for the SET_PORT command wrapper (so that slaves may modify their GIDS
for RoCE).

This requires the following modifications:
1. Fix build_mlx4_header to properly fill in the ETH fields
2. Adjust mux and demux QP1 flow to support RoCE.
This commit still assumes only one GID per slave for RoCE.
The commit enabling multiple GIDs is a subsequent commit, and
is done separately because of its complexity.

priv is not instantiated at gfar_of_init() time, when
parsing the DT for info on supported HW queues. Before
the netdev can be allocated, the number of supported
queues must be known. Because the number of supported
queues depends on device type, move the compatibility
checks before netdev allocation. Local vars are used
to hold the operation mode info before netdev allocation.
This fixes the null accesses for priv->.., in gfar_of_init.

rf233 is missing some features that rf231 has, but we don't currently
make use of them so there's nothing to handle differently yet.
Should we add support in the future for rf231 *_NOCLK or SLEEP states,

For the "fsl,etsec2" compatible models the driver currently
supports 8 Tx and Rx DMA rings (aka HW queues). However, there
are only 2 pairs of Rx/Tx interrupt lines, as these controllers
are integrated in low power SoCs with 2 CPUs at most. As a result,
there are at most 2 NAPI instances that have to service multiple
Tx and Rx queues for these devices. This complicates the NAPI
polling routine having to iterate over the mutiple Rx/Tx queues
hooked to the same interrupt lines. And there's also an overhead
at HW level, as the controller needs to service all the 8 Tx rings
in a round robin manner. The combined overhead shows up for multi
parallel Tx flows transmitted by the kernel stack, when the driver
usually starts returning NETDEV_TX_BUSY leading to NETDEV WATCHDOG
Tx timeout triggering if the Tx path is congested for too long.
As an alternative, this patch makes the driver support only one
Tx/Rx DMA ring per NAPI instance (per interrupt group or pair
of Tx/Rx interrupt lines) by default. The simplified single queue
polling routine (gfar_poll_sq) will be the default napi poll routine
for the etsec2 devices too. Some adjustments needed to be made to
link the Tx/Rx HW queues with each NAPI instance (2 in this case).
The gfar_poll_sq() is already successfully used by older SQ_SG_MODE
(single interrupt group) controllers.
This patch fixes Tx timeout triggering under heavy Tx traffic load
(i.e. iperf -c -P 8) for the "fsl,etsec2" (currently the only
MQ_MG_MODE devices). There's also a significant memory footprint
reduction by supporting 2 Rx/Tx DMA rings (at most), instead of 8,
for these devices.

There are some concurrency issues on devices w/ 2 CPUs related
to the handling of Rx and Tx interrupts. eTSEC has separate
interrupt lines for Rx and Tx but a single imask register
to mask these interrupts and a single NAPI instance to handle
both Rx and Tx work. As a result, the Rx and Tx ISRs are
identical, both are invoking gfar_schedule_cleanup(), however
both handlers can be entered at the same time when the Rx and
Tx interrupts are taken by different CPUs. In this case
spurrious interrupts (SPU) show up (in /proc/interrupts)
indicating a concurrency issue. Also, Tx overruns followed
by Tx timeout have been observed under heavy Tx traffic load.
To address these issues, the schedule cleanup ISR part has
been changed to handle the Rx and Tx interrupts independently.
The patch adds a separate NAPI poll routine for Tx cleanup to
be triggerred independently by the Tx confirmation interrupts
only. Existing poll functions are modified to handle only
the Rx path processing. The Tx poll routine does not need a
budget, since Tx processing doesn't consume NAPI budget, and
hence it is registered with minimum NAPI weight.
NAPI scheduling does not require locking since there are
different NAPI instances between the Rx and Tx confirmation
paths now.
So, the patch fixes the occurence of spurrious Rx/Tx interrupts.
Tx overruns also occur less frequently now.

Previous commit c3a0dce35af0 fixed an overrun for the RAR on i218 devices.
This commit also attempted to homogenize the RAR/SHRA access for all parts
accessed by the e1000e driver. This change introduced an error for
assigning MAC addresses to guest OS's for 82579 devices.
Only RAR[0] is accessible to the driver for 82579 parts, and additional
addresses must be placed into the SHRA[L|H] registers. The rar_entry_count
was changed in the previous commit to an inaccurate value that accounted
for all RAR and SHRA registers, not just the ones usable by the driver.
This patch fixes the count to the correct value and adjusts the
e1000_rar_set_pch2lan() function to user the correct index.

Valid values for InterruptThrottleRate are 10-100000, or one of
0, 1, 3, 4. '2' is not valid. This is a legacy from the branching
from the e1000 driver code that e1000e was based from.
Prior to this patch, if the e1000e driver was loaded with a forced
invalid InterruptThrottleRate of '2', then no throttle rate would be
set and no error message generated.
Now, a message will be generated that an invalid value was used and the
value for InterruptThrottleRate will be set to the default value.

ULP is a power saving feature that reduces the power consumption of the
PHY when a cable is not connected.
ULP is gated on the following conditions:
1) The hardware must support ULP. Currently this is only I218
devices from Intel
2) ULP is initiated by the driver, so, no driver results in no ULP.
3) ULP's implementation utilizes Runtime Power Management to toggle its
execution. ULP is enabled/disabled based on the state of Runtime PM.
4) ULP is not active when wake-on-unicast, multicast or broadcast is active
as these features are mutually-exclusive.
Since the PHY is in an unavailable state while ULP is active, any access
of the PHY registers will fail. This is resolved by utilizing kernel
calls that cause the device to exit Runtime PM (e.g. pm_runtime_get_sync)
and then, after PHY access is complete, allow the device to resume
Runtime PM (e.g. pm_runtime_put_sync).
Under certain conditions, toggling the LANPHYPC is necessary to disable
ULP mode. Break out existing code to toggle LANPHYPC to a new function
to avoid code duplication.

set the individual dev_pm_ops callbacks for suspend, resume, freeze,
thaw, poweroff and restore.
Add a boolean parameter (reset) to the e1000e_down function to allow

On a ME enabled system with the cable out, the driver init flow would
generate an erroneous message indicating that resets were being blocked
by an active ME session. Cause was ME clearing the semaphore bit to
block further PHY resets for up to 50 msec during power-on/cycle. After
this interval, ME would re-set the bit and allow PHY resets.
To resolve this, change the flow of e1000e_phy_hw_reset_generic() to
utilize a delay and retry method. Poll the FWSM register to minimize
any extra time added to the flow. If the delay times out at 100ms
(checked in 10msec increments), then return the value E1000_BLK_PHY_RESET,
as this is the accurate state of the PHY. Attempting to alter just the
call to e1000e_phy_hw_reset_generic() in e1000_init_phy_workarounds_pchlan()
just caused the problem to move further down the flow.
