BNXT only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get(). The conversion is
straight forward here since the PF and VF code use the same getter.
Since bnxt makes uses of switchdev_port_same_parent_id() convert it to
use netdev_port_same_parent_id().

This patch provides the flow_stats structure that acts as container for
tc_cls_flower_offload, then we can use to restore the statistics on the
existing TC actions. Hence, tcf_exts_stats_update() is not used from

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

All users of the fixed_phy_add() pass -1 as GPIO number
to the fixed phy driver, and all users of fixed_phy_register()
pass -1 as GPIO number as well, except for the device
tree MDIO bus.
Any new users should create a proper device and pass the
GPIO as a descriptor associated with the device so delete
the GPIO argument from the calls and drop the code looking
requesting a GPIO in fixed_phy_add().
In fixed phy_register(), investigate the "fixed-link"
node and pick the GPIO descriptor from "link-gpios" if
this property exists. Move the corresponding code out
of of_mdio.c as the fixed phy code anyways requires
OF to be in use.

Register devlink_port with devlink and create initial port params
table for bnxt_en. The table consists of a generic parameter:
wake_on_lan: Enables Wake on Lan for this port when magic packet
is received with this port's MAC address using ACPI pattern.
If enabled, the controller asserts a wake pin upon reception of
WoL packet. ACPI (Advanced Configuration and Power Interface) is
an industry specification for the efficient handling of power
consumption in desktop and mobile computers.
v2->v3:
- Modify bnxt_dl_wol_validate(), to throw error message when user gives
value other than DEVLINK_PARAM_WAKE_MAGIC ot to disable WOL.
- Use netdev_err() instead of netdev_warn(), when devlink_port_register()
and devlink_port_params_register() returns error. Also, don't log rc
in this message.

The skb should be freed by dev_consume_skb_any() in b44_start_xmit()
when bounce_skb is used. The skb is be replaced by bounce_skb, so the
original skb should be consumed(not drop).
dev_consume_skb_irq() should be called in b44_tx() when skb xmit
done. It makes drop profiles(dropwatch, perf) more friendly.

When allocating memory pages for context memory, if the last page table
should be fully populated, the current code will set nr_pages to 0 when
calling bnxt_alloc_ctx_mem_blk(). This will cause the last page table
to be completely blank and causing some RDMA failures.
Fix it by setting the last page table's nr_pages to the remainder only
if it is non-zero.

#define CHIP_NUM_57711 0x164f
#define CHIP_NUM_57711E 0x1650

Older firmware only supports 16-bit flow handle, because of which the
number of flows that can be offloaded can’t scale beyond a point.
Newer firmware supports 64-bit flow handle enabling the host to scale
upto millions of flows. With the new 64-bit flow handle support, driver
has to query flow stats in a different way compared to the older approach.
This patch adds support for 64-bit flow handle and new way to query
flow stats.

Earlier, some of the firmware commands (ex: CFA_FLOW_*) which are processed
by KONG processor were sent to the CHIMP processor from the host. This
approach was taken as there was no direct message channel to KONG.
CHIMP in turn used to send them to KONG. Newer firmware supports a new
message channel which the host can send messages directly to the KONG
processor.
This patch adds support for required changes needed in the driver
to support direct KONG message channel. This speeds up flow related
messages sent to the firmware for CLS_FLOWER offload.

The current code has 2 problems. It assumes that the RX ring for
the loopback packet is combined with the TX ring. This is not
true if the ethtool channels are set to non-combined mode. The
second problem is that it won't work on 57500 chips without
adjusting the logic to get the proper completion ring (cpr) pointer.

When bringing up a device, the code checks to see if the number of

changing the number of reserved NQs/CMPL rings. This ensures that
the MSIX vectors associated with the NQs/CMPL rings are still
properly mapped when pci_disable_msix() masks the vectors.
This patch will prevent errors when RDMA support is added for the new

decreased and we must use the new sequence to prevent MSIX errors.

Drivers may not be able to implement a VLAN addition or reconfiguration.
In those cases it's desirable to explain to the user that it was
rejected (and why).
To that end, add extack argument to ndo_bridge_setlink. Adapt all users
to that change.
Following patches will use the new argument in the bridge driver.

The message above is commonly seen when a newer driver is used on
hardware with older firmware. The issue is this message means nothing to
anyone except Broadcom. Remove the message to not confuse users as this
message is really not very informative.

Driver sends update-SVID ramrod in the MFW notification path.
If there is a pending ramrod, driver doesn't retry the command
and storm firmware will never be updated with the SVID value.
The patch adds changes to send update-svid ramrod in process context with
retry/poll flags set.

There will be only one PHC clock per port. PTP should be enabled only on
one PF per port. The change enables PTP functionality on the PF that
initializes the port. The change is useful in multi-function modes e.g.,
NPAR where a port can have more than one PF.

Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.

On some customer setups it was observed that shmem contains a non-zero fip
MAC for 57711 which would lead to enabling of SW FCoE.
Add a software workaround to clear the bad fip mac address if no FCoE
connections are supported.
