Signed-off-by: Alex Elder <elder@linaro.org>
Signed-off-by: David S. Miller <davem@davemloft.net>
Starting with IPA v4.5, IP payload checksum offload is implemented
differently.
Prior to v4.5, the IPA hardware appends an rmnet_map_dl_csum_trailer
structure to each packet if checksum offload is enabled in the
download direction (modem->AP). In the upload direction (AP->modem)
a rmnet_map_ul_csum_header structure is prepended before each sent
packet.
Starting with IPA v4.5, checksum offload is implemented using a
single new rmnet_map_v5_csum_header structure which sits between
the QMAP header and the packet data. The same header structure
is used in both directions.
The new header contains a header type (CSUM_OFFLOAD); a checksum
flag; and a flag indicating whether any other headers follow this
one. The checksum flag indicates whether the hardware should
compute (and insert) the checksum on a sent packet. On a received
packet the checksum flag indicates whether the hardware confirms the
checksum value in the payload is correct.

OFLD and CTRL TX queues can be stopped if there is no room in
their DMA rings. If this happens, they're tried to be restarted
later after having made some room in the corresponding ring.
The tasks of restarting these queues were triggered using
tasklets, but they can be replaced for workqueue works, getting
them out of softirq context.
This queues stop/restart probably doesn't happen often and they
can be quite lengthy because they try to send all pending skbs.
Moreover, given that probably the ring is not empty yet, so the
DMA still has work to do, we don't need to be so fast to justify
using tasklets/softirq instead of running in a thread.

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.

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.

With this change, the needed SQ stop room size drops by 31.

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.

Initialize structs to avoid unexpected behavior.
No immediate issue in current code, structs are return values, it's
safer to initialize.
