Currently SW steering doesn't have the means to access HW iterators to
support multi-destination (FTEs) flow table entries.
In order to support multi-destination FTEs for port-mirroring, SW
steering will create a dedicated multi-destination FW managed flow table
and FTEs via direct FW commands that we introduced in the previous patch.

mlx5_core_destroy_cq() mlx5_eq_comp_int()
mlx5_eq_del_cq() [..]
radix_tree_delete() [..]
[..] mlx5_eq_cq_get() /* Didn't find CQ is

/* destroy CQ in hw */
mlx5_cmd_exec()
This is still a valid scenario and correct delete CQ sequence, as
mirror of the CQ create sequence.

Currently the max number of channels is limited to 64, which is half of
the indirection table size to allow some flexibility. But on servers
with more than 64 cores, users may want to utilize more queues.
This patch increases the advertised max number of channels to 128 by
changing the ratio between channels and indirection table slots to 1:1.
At the same time, the driver still enable no more than 64 channels at
loading. Users can change it by ethtool afterwards.

In some configurations, gcc tries too hard to optimize this code:
drivers/net/ethernet/mellanox/mlx5/core/en_stats.c: In function 'mlx5e_grp_sw_update_stats':
drivers/net/ethernet/mellanox/mlx5/core/en_stats.c:302:1: error: the frame size of 1336 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
As was stated in the bug report, the reason is that gcc runs into a corner
case in the register allocator that is rather hard to fix in a good way.
As there is an easy way to work around it, just add a comment and the
barrier that stops gcc from trying to overoptimize the function.

Unlike most networking drivers using begin() and complete() ethtool_ops
callbacks to resume a device which is down and suspend it again when done,
epic100 does not use standard refcounted infrastructure but sets device
sleep state directly.
With the introduction of netlink ethtool interface, we may have nested
begin-complete blocks so that inner complete() would put the device back to
sleep for the rest of the outer block.
To avoid rewriting an old and not very actively developed driver, just add
a nesting counter and only perform resume and suspend on the outermost
level.

In hclge_inform_reset_assert_to_vf(), variable reset_type(enum type)
will be copied into msg_data whose size is 2 bytes. Currently, hip08
is a little-endian machine, so the lower two bytes of reset_type will
be copied to msg_data. But when running on a big-endian machine,
msg_data will have a wrong value(the higher two bytes of reset_type).
So this patch modifies the type of reset_type to u16, and adds a
build check in case enum hnae3_reset_type has value larger than
U16_MAX.

When rename the net devices, the IRQ number can not be

The Ocelot switchdev driver and the Felix DSA one need it for different
reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is
integrated with the traditional NXP Layerscape PCS design which does not
support runtime configuration of SerDes protocol. So it needs to
pre-validate the phy-mode from the device tree and prevent PHYLINK from
attempting to change it. For this, it needs to cache it in a private
variable.

This increases the MDIO hold time to 5 enet_clk cycles from the previous
value of 0. This is actually the out-of-reset value, that the driver was
previously overwriting with 0. Zero worked for the external MDIO, but

ENETC SI's and Felix switch are found.

Within the LS1028A SoC, the register map for the ENETC MDIO controller
is instantiated a few times: for the central (external) MDIO controller,
for the internal bus of each standalone ENETC port, and for the internal
bus of the Felix switch.
Refactoring is needed to support multiple MDIO buses from multiple
drivers. The enetc_hw structure is made an opaque type and a smaller
enetc_mdio_priv is created.
'mdio_base' - MDIO registers base address - is being parameterized, to
be able to work with different MDIO register bases.
The ENETC MDIO bus operations are exported from the fsl-enetc-mdio
kernel object, the same that registers the central MDIO controller (the
dedicated PF). The ENETC main driver has been changed to select it, and
use its exported helpers to further register its private MDIO bus. The
DSA Felix driver will do the same.

Switch network drivers, phy drivers, and SFP/phylink over to use the
more correct 10GBASE-R, rather than 10GBASE-KR. 10GBASE-KR is backplane
ethernet, which is 10GBASE-R with autonegotiation on top, which our
current usage on the affected platforms does not have.
The only remaining user of PHY_INTERFACE_MODE_10GKR is the Aquantia
PHY, which has a separate mode for 10GBASE-KR.
For Marvell mvpp2, we detect 10GBASE-KR, and rewrite it to 10GBASE-R
for compatibility with existing DT - this is the only network driver
at present that makes use of PHY_INTERFACE_MODE_10GKR.

Coverity reports some of the calls to xdp_rxq_info_reg() as potential
issues, because the driver does not check its return value. However,
those calls are wrapped with "if (!xdp_rxq_info_is_reg(&ring->xdp_rxq))"
and this check alone is enough to be sure that the function will never

All possible states of xdp_rxq_info are:
- NEW,
- REGISTERED,
- UNREGISTERED,
- UNUSED.
The driver won't mark a queue as UNUSED under no circumstance, so the
