In this patch, we present the IO level functionality.
The nvme-tcp-offload shall work on the IO-level, meaning the
nvme-tcp-offload ULP module shall pass the request to the nvme-tcp-offload
vendor driver and shall expect for the request completion.
No additional handling is needed in between, this design will reduce the
CPU utilization as we will describe below.
The nvme-tcp-offload vendor driver shall register to nvme-tcp-offload ULP
with the following IO-path ops:
- send_req - in order to pass the request to the handling of the offload
driver that shall pass it to the vendor specific device
- poll_queue
The vendor driver will manage the context from which the request will be
executed and the request aggregations.
Once the IO completed, the nvme-tcp-offload vendor driver shall call
command.done() that shall invoke the nvme-tcp-offload ULP layer for
completing the request.
This patch also add support for the nvme-tcp-offload timeout and
nvme-tcp-offload ASYNC flow.

In this patch we implement queue level functionality.
The implementation is similar to the nvme-tcp module, the main
difference being that we call the vendor specific create_queue op which
creates the TCP connection, and NVMeTPC connection including
icreq+icresp negotiation.
Once create_queue returns successfully, we can move on to the fabrics
connect.

In this patch, we implement controller level error handling and recovery.
Upon an error discovered by the ULP or reset controller initiated by the

In this patch we implement controller level functionality including:
- create_ctrl.
- delete_ctrl.
- free_ctrl.
The implementation is similar to other nvme fabrics modules, the main
difference being that the nvme-tcp-offload ULP calls the vendor specific
claim_dev() op with the given TCP/IP parameters to determine which device
will be used for this controller.
Once found, the vendor specific device and controller will be paired and
kept in a controller list managed by the ULP.

the connection params. Once the correct devices is found (claim_dev
returns true), we raise the refcnt of that device and return that device
as the device to be used for ctrl currently being created.

nvmf_check_required_opts() is used to check if user provided opts has
the required_opts or not. if not, it will log which options are not
provided.
It can be leveraged by nvme-tcp-offload to check if provided opts are

Move NVMF_ALLOWED_OPTS and NVMF_REQUIRED_OPTS definitions
to header file, so it can be used by the different HW devices.
NVMeTCP offload devices might have different limitations of the
allowed options, for example, a device that does not support all the
queue types. With tcp and rdma, only the nvme-tcp and nvme-rdma layers
handle those attributes and the HW devices do not create any limitations
for the allowed options.
An alternative design could be to add separate fields in
nvme_tcp_ofld_ops such as max_hw_sectors and max_segments that
we already have in this series.

This patch will present the structure for the NVMeTCP offload common
layer driver. This module is added under "drivers/nvme/host/" and future
offload drivers which will register to it will be placed under
"drivers/nvme/hw".
This new driver will be enabled by the Kconfig "NVM Express over Fabrics
TCP offload commmon layer".
In order to support the new transport type, for host mode, no change is
needed.
Each new vendor-specific offload driver will register to this ULP during
its probe function, by filling out the nvme_tcp_ofld_dev->ops and
nvme_tcp_ofld_dev->private_data and calling nvme_tcp_ofld_register_dev
with the initialized struct.
The internal implementation:
- tcp-offload.h:
Includes all common structs and ops to be used and shared by offload
drivers.
- tcp-offload.c:
Includes the init function which registers as a NVMf transport just
like any other transport.

Since all the remaining members of struct mdio_xpcs_ops have direct
equivalents in struct phylink_pcs_ops, it is about time we remove it
altogether.
Since the phylink ops return void, we need to remove the error
propagation from the various xpcs methods and simply print an error
message where appropriate.
Since xpcs_get_state_c73() detects link faults and attempts to reset the
link on its own by calling xpcs_config(), but xpcs_config() now has a
lot of phylink arguments which are not needed and cannot be simply
fabricated by anybody else except phylink, the actual implementation has
been moved into a smaller xpcs_do_config().
The const struct mdio_xpcs_ops *priv->hw->xpcs has been removed, so we
need to look at the struct mdio_xpcs_args pointer now as an indication
whether the port has an XPCS or not.

Unify the 2 existing PCS drivers (lynx and xpcs) by doing a similar
thing on probe, which is to have a *_create function that takes a
struct mdio_device * given by the caller, and builds a private PCS
structure around that.
This changes stmmac to hold only a pointer to the xpcs, as opposed to
the full structure. This will be used in the next patch when struct
mdio_xpcs_ops is removed. Currently a pointer to struct mdio_xpcs_ops
is used as a shorthand to determine whether the port has an XPCS or not.
We can do the same now with the mdio_xpcs_args pointer.

Calling a function pointer with a single implementation through

Simply remove the "validate" function pointer from struct mdio_xpcs_ops

The operating mode of the driver is currently to populate its
struct mdio_xpcs_args::supported and struct mdio_xpcs_args::an_mode
statically in xpcs_probe(), based on the passed phy_interface_t,
and work with those.
However this is not the operation that phylink expects from a PCS
driver, because the port might be attached to an SFP cage that triggers
changes of the phy_interface_t dynamically as one SFP module is
unpluggged and another is plugged.
To migrate towards that model, the struct mdio_xpcs_args should not
cache anything related to the phy_interface_t, but just look up the
statically defined, const struct xpcs_compat structure corresponding to
the detected PCS OUI/model number.
So we delete the "supported" and "an_mode" members of struct
mdio_xpcs_args, and add the "id" structure there (since the ID is not
expected to change at runtime).
Since xpcs->supported is used deep in the code in _xpcs_config_aneg_c73(),
we need to modify some function headers to pass the xpcs_compat from all
callers. In turn, the xpcs_compat is always supplied externally to the
xpcs module:
- Most of the time by phylink
- In xpcs_probe() it is needed because xpcs_soft_reset() writes to
MDIO_MMD_PCS or to MDIO_MMD_VEND2 depending on whether an_mode is clause
37 or clause 73. In order to not introduce functional changes related
to when the soft reset is issued, we continue to require the initial
phy_interface_t argument to be passed to xpcs_probe() so we can pass
this on to xpcs_soft_reset().
- stmmac_open() wants to know whether to call stmmac_init_phy() or not,
and for that it looks inside xpcs->an_mode, because the clause 73
(backplane) AN modes supposedly do not have a PHY. Because we moved
an_mode outside of struct mdio_xpcs_args, this is now no longer
directly possible, so we introduce a helper function xpcs_get_an_mode()
which protects the data encapsulation of the xpcs module and requires
a phy_interface_t to be passed as argument. This function can look up
the appropriate compat based on the phy_interface_t.

The xpcs driver has an apparently inadequate structure for the actual
hardware it drives.
These defines and the xpcs_probe() function would suggest that there is
one PHY ID per supported PHY interface type, and the driver simply
validates whether the mode it should operate in (the argument of
xpcs_probe) matches what the hardware is capable of:
#define SYNOPSYS_XPCS_USXGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_10GKR_ID 0x7996ced0
#define SYNOPSYS_XPCS_XLGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_SGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_MASK 0xffffffff
but that is not the case, because upon closer inspection, all the above
4 PHY ID definitions are in fact equal.
So it is the same XPCS that is compatible with all 4 sets of PHY
interface types.
This change introduces an array of struct xpcs_compat which is populated
by the single struct xpcs_id instance. It also eliminates the bogus
defines for multiple Synopsys XPCS PHY IDs and replaces them with a
single XPCS_ID, which better reflects the way in which the hardware
operates.
Because we are touching this area of the code anyway, the new array of
struct xpcs_compat, as well as the array of xpcs_id, have been moved
towards the end of the file, since they are variable declarations not
definitions. If whichever of struct xpcs_compat or struct xpcs_id need
to gain a function pointer member in the future, it is easier to
reference functions (no forward declarations needed) if we have the
const variable declarations at the end of the file.

After some commits, mlx5e_txwqe_build_eseg() lost its ability to return
boolean value and became effectively void.

Under kdump environment we want to use the smallest possible amount
of resources, that includes setting SQ size to minimum.
However, when running on a device that supports TLS device offload,
then the SQ stop room becomes larger than with non-capable device and
requires increasing the SQ size.
Since TLS device offload is not necessary in kdump mode, disable it to
reduce the memory requirements for capable devices.
With this change, the needed SQ stop room size drops by 33.

Move the logic that updates the page pool upon changes in numa node.
Before this patch, logic was placed in the RX polling function, being
called also when no RX traffic, wasting cpu cycles. Here we move it to
the RX post_wqes function, to be called only when new RX descriptors are
going to be allocated.

mlx5 devices were observed generating MLX5_PORT_CHANGE_SUBTYPE_ACTIVE
events without an intervening MLX5_PORT_CHANGE_SUBTYPE_DOWN. This
breaks link flap detection based on Linux carrier state transition
count as netif_carrier_on() does nothing if carrier is already on.
Make sure we count such events.
netif_carrier_event() increments the counters and fires the linkwatch
events. The latter is not necessary for the use case but seems like
the right thing to do.

Instead of programming all SID overrides during early boot, perform the
operation on-demand after the SMMU translations have been set up for a
device. This reuses data from device tree to match memory clients for a
device and programs the SID specified in device tree, which corresponds
to the SID used for the SMMU context banks for the device.
