net/mlx5: HW Steering cleanups
This short series by Yevgeny contains several small HW Steering cleanups:
- Patch 1: removing unused FW commands
- Patch 2: using list_move() instead of list_del/add
- Patch 3: printing the unsupported combination of match fields

====================
net: stmmac: deprecate "snps,en-tx-lpi-clockgating" property
This series deprecates the "snps,en-tx-lpi-clockgating" property for
stmmac.
MII Transmit clock gating, where the MAC hardware supports gating this
clock, is a function of the connected PHY capabilities, which it
reports through its status register.
GMAC versions that support transmit clock gating twiddle the LPITCSE
bit accordingly in the LPI control/status register, which is handled
by the GMAC core specific code.
So, "snps,en-tx-lpi-clockgating" not something that is a GMAC property,
but is a work-around for phylib not providing an interface to determine
whether the PHY allows the transmit clock to be disabled.
This series converts the two SoCs that make use of this property (which,
I hasten to add, is set in the SoC code) to use the PHY capability bit
instead of a DT property, then removes the DT property from the .dtsi,
deprecates it in the snps,dwmac binding, and finally in the stmmac code.
I am expecting some discussion on how to merge this, as I think the
order in which these changes is made is important - we don't want to
deprecate the old way until the new code has landed.

Whether the MII transmit clock can be stopped is primarily a property
of the PHY (there is a capability bit that should be checked first.)
Whether the MAC is capable of stopping the transmit clock is a separate
issue, but this is already handled by the core DesignWare MAC code.
Therefore, snps,en-tx-lpi-clockgating is technically incorrect, and
this commit adds a warning should a DT be encountered with the property
present.
However, we keep backwards compatibility.

drives fails to be detected on a warm boot when LPM is enabled.
LPM on ATI AHCI works fine with other drives. Likewise, the
Samsung drives works fine with LPM with other AHI controllers.
Thus, just like the weirdo ATA_QUIRK_NO_NCQ_ON_ATI quirk, add a
new ATA_QUIRK_NO_LPM_ON_ATI quirk to disable LPM only on ATI
AHCI controllers.

net: stmmac: remove unnecessary of_get_phy_mode() calls
This series removes unnecessary of_get_phy_mode() calls from the stmmac
glue drivers. stmmac_probe_config_dt() / devm_stmmac_probe_config_dt()
already gets the interface mode using device_get_phy_mode() and stores
it in plat_dat->phy_interface.
Therefore, glue drivers using of_get_phy_mode() are just duplicating
the work that has already been done.
This series adjusts the glue drivers to remove their usage of
of_get_phy_mode().

sun8i was using of_get_phy_mode() to set plat_dat->mac_interface, which
defaults to plat_dat->phy_interface when the mac-mode DT property is
not present. As nothing in arch/*/boot/dts sets the mac-mode property,
it is highly likely that these two will be identical, and thus there
is no need for this glue driver to set plat_dat->mac_interface.

put in sock_read_tx group (for good reasons).
Then dst_metric(dst, RTAX_QUICKACK) also needs extra cache line misses.

====================
udp_tunnel: GRO optimizations
The UDP tunnel GRO stage is source of measurable overhead for workload
based on UDP-encapsulated traffic: each incoming packets requires a full
UDP socket lookup and an indirect call.
In the most common setups a single UDP tunnel device is used. In such
case we can optimize both the lookup and the indirect call.
Patch 1 tracks per netns the active UDP tunnels and replaces the socket
lookup with a single destination port comparison when possible.
Patch 2 tracks the different types of UDP tunnels and replaces the
indirect call with a static one when there is a single UDP tunnel type
active.
I measure ~5% performance improvement in TCP over UDP tunnel stream
tests on top of this series.

It's quite common to have a single UDP tunnel type active in the
whole system. In such a case we can replace the indirect call for
the UDP tunnel GRO callback with a static call.
Add the related accounting in the control path and switch to static
call when possible. To keep the code simple use a static array for
the registered tunnel types, and size such array based on the kernel
config.

Most UDP tunnels bind a socket to a local port, with ANY address, no
peer and no interface index specified.
Additionally it's quite common to have a single tunnel device per
namespace.
Track in each namespace the UDP tunnel socket respecting the above.
When only a single one is present, store a reference in the netns.
When such reference is not NULL, UDP tunnel GRO lookup just need to
match the incoming packet destination port vs the socket local port.
The tunnel socket never sets the reuse[port] flag[s]. When bound to no
address and interface, no other socket can exist in the same netns
matching the specified local port.
Matching packets with non-local destination addresses will be
aggregated, and eventually segmented as needed - no behavior changes
intended.
Note that the UDP tunnel socket reference is stored into struct
netns_ipv4 for both IPv4 and IPv6 tunnels. That is intentional to keep
all the fastpath-related netns fields in the same struct and allow
cacheline-based optimization. Currently both the IPv4 and IPv6 socket
pointer share the same cacheline as the `udp_table` field.

According to GDMA protocol, holes (zeros) are allowed at the beginning
or middle of the gdma_list_devices_resp message. The existing code
cannot properly handle this, and may miss some devices in the list.
To fix, scan the entire list until the num_of_devs are found, or until
the end of the list.

Registering the interrupts for TX or RX DMA Channels prior to registering
their respective NAPI callbacks can result in a NULL pointer dereference.
This is seen in practice as a random occurrence since it depends on the
randomness associated with the generation of traffic by Linux and the
reception of traffic from the wire.

mlx5: Support setting a parent for a devlink rate node
This series by Carolina adds mlx5 support for the setting of a parent to
devlink rate nodes.
By introducing a hierarchical level to scheduling nodes, these changes
allow for more granular control over bandwidth allocation and isolation
of Virtual Functions.
Function renaming for parent setting on leafs:
- net/mlx5: Rename devlink rate parent set function for leaf nodes
Add support for hierarchy level tracking:
- net/mlx5: Introduce hierarchy level tracking on scheduling nodes
- net/mlx5: Preserve rate settings when creating a rate node
Support setting parent for rate nodes:

Introduce `mlx5_esw_devlink_rate_node_parent_set()` to allow assigning
a parent to scheduling nodes.
Implement `mlx5_esw_qos_node_update_parent()` and
`mlx5_esw_qos_node_validate_set_parent()` to enforce constraints on
node reassignment.
Don't allow reassignment of nodes with active rate objects.
Update `esw_qos_node_set_parent()` to handle cases where
the parent is NULL. A NULL parent indicates that the scheduling element
is attached to the root scheduling element, and since only rate nodes
can be connected to the root, this update is now necessary.
