As we don't specify the MTU in the driver, the framework
will fall back to 1500 bytes and this doesn't work very
well when we try to attach a DSA switch:
eth1: mtu greater than device maximum
ixp4xx_eth c800a000.ethernet eth1: error -22 setting
MTU to 1504 to include DSA overhead
After locating an out-of-tree patch in OpenWrt I found
suitable code to set the MTU on the interface and ported
it and updated it. Now the MTU gets set properly.

The previous patches prepared the code to allow separating between
choosing blocks and filling blocks.
Do not add blocks as part of the loop that chooses them. When all the
required blocks are set in the bitmap 'chosen_blocks_bm', start filling
blocks. Iterate over the bitmap twice - first add only blocks that are
marked with 'high_entropy' flag. Then, fill the rest of the blocks.
The idea is to place key blocks with high entropy in blocks 0 to 5. See
more details in previous patches.

Currently, mlxsw_afk_picker() chooses which blocks will be used for a
given list of elements, and fills the blocks during the searching - when a
key block is found with most hits, it adds it and removes the elements from
the count of hits. This should be changed as we want to be able to choose
which blocks will be placed in blocks 0 to 5.
To separate between choosing blocks and filling blocks, several pre-changes
are required. Currently, the indication of whether all elements were
found in the chosen blocks is by the structure 'key_info->elusage'. This
structure is updated when block is filled as part of
mlxsw_afk_picker_key_info_add(). A following patch will call this
function only after choosing all the blocks. Add a bitmap called
'elusage_chosen' to store which elements were chosen in the chosen blocks.
Change the condition in the loop to check elements that were chosen, not
elements that were already filled in the blocks.

For 12 key blocks in the A-TCAM, rules are split into two records, which
constitute two lookups. The two records are linked using a
"large entry key ID".
Due to a Spectrum-4 hardware issue, KVD entries that correspond to key
blocks 0 to 5 of 12 key blocks A-TCAM entries will be placed in the same
KVD pipe if they only differ in their "large entry key ID", as it is
ignored. This results in a reduced scale. To reduce the probability of this
issue, we can place key blocks with high entropy in blocks 0 to 5. The idea
is to place blocks that are changed often in blocks 0 to 5, for
example, key blocks that match on IPv4 addresses or the LSBs of IPv6
addresses. Such placement will reduce the probability of these blocks to be
same.
Mark several blocks with 'high_entropy' flag, so later we will take into
account this flag and place them in blocks 0 to 5.

When a foreign LHS rule (TC rule from a tunnel netdev which requests
conntrack lookup) matches on inner headers or enc_key_id, these matches
cannot be performed by the Outer Rule table, as the keys are only
available after the tunnel type has been identified (by the OR lookup)
and the rest of the headers parsed accordingly.
Offload such rules with an Action Rule, using the LOOKUP_CONTROL section
of the AR response to specify the conntrack and/or recirculation actions,
combined with an Outer Rule which performs only the usual Encap Match
duties.
This processing flow, as it requires two AR lookups per packet, is less
performant than OR-CT-AR, so only use it where necessary.

There were a few places where no extack error message was set, or the
extack was not forwarded to callees, potentially resulting in a return
of -EOPNOTSUPP with no additional information.
Make sure to populate the error message in these cases. In practice
this does us no good as TC indirect block callbacks don't come with an
extack to fill in; but maybe they will someday and when debugging it's
possible to provide a fake extack and emit its message to the console.

Normally, if a TC filter on a tunnel netdev does not match on any
encap fields, we decline to offload it, as it cannot meet our
requirement for a <sip,dip,dport> tuple for the encap match.
However, if the rule has a nonzero chain_index, then for a packet to
reach the rule, it must already have matched a LHS rule which will
have included an encap match and determined the tunnel type, so in
that case we can offload the right-hand-side rule.

To ensure this rule does not overlap with other tunnel rules on the same

(EFX_TC_EM_PSEUDO_OR), which unlike PSEUDO_MASK may only be referenced

Similarly as for ice driver [1] there are also circular header
dependencies in i40e driver:
i40e.h -> i40e_virtchnl_pf.h -> i40e.h
Another issue is that i40e header files does not contain their own
dependencies on other header files (both private and standard) so their
inclusion in .c file require to add these deps in certain order to
that .c file to make it compilable.
Fix both issues by removal the mentioned circular dependency, by filling
i40e headers with their dependencies so they can be placed anywhere in
a source code. Additionally remove bunch of includes from i40e.h super
header file that are not necessary and include i40e.h only in .c files

While searching for possible refactor of napi_schedule_prep and
__napi_schedule it was notice that the mtk eth driver disable the
interrupt for rx and tx AFTER napi is scheduled.
While this is a very hard to repro case it might happen to have
situation where the interrupt is disabled and never enabled again as the
napi completes and the interrupt is enabled before.
This is caused by the fact that a napi driven by interrupt expect a
logic with:
1. interrupt received. napi prepared -> interrupt disabled -> napi
scheduled
2. napi triggered. ring cleared -> interrupt enabled -> wait for new
interrupt
To prevent this case, disable the interrupt BEFORE the napi is
scheduled.

The STM32MP1 keeps clk_rx enabled during suspend, and therefore the
driver does not enable the clock in stm32_dwmac_init() if the device was
suspended. The problem is that this same code runs on STM32 MCUs, which
do disable clk_rx during suspend, causing the clock to never be
re-enabled on resume.
This patch adds a variant flag to indicate that clk_rx remains enabled
during suspend, and uses this to decide whether to enable the clock in
stm32_dwmac_init() if the device was suspended.
This approach fixes this specific bug with limited opportunity for
unintended side-effects, but I have a follow up patch that will refactor
the clock configuration and hopefully make it less error prone.

ld: vmlinux.o: in function `ice_dpll_init':
(.text+0x8953d5): undefined reference to `ice_get_cgu_rclk_pin_info'
The first commit broke things by calling functions in
ice_init_feature_support that are compiled as part of ice_ptp_hw.o,
including:
* ice_is_phy_rclk_present
* ice_is_clock_mux_present_e810t
* ice_is_cgU_present
The second commit continued the break by calling several CGU functions
defined in ice_ptp_hw.c in the DPLL code.
Because the ice_dpll.c file is compiled unconditionally, it will not
link when CONFIG_PTP_1588_CLOCK=n.
It might be possible to break this dependency and expose those functions
without CONFIG_PTP_1588_CLOCK, but that is not clear to me.
For the DPLL case, simply compile ice_dpll.o only when we have
CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and
ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h
The other functions are part of checking the netlist to see if hardware
features are enabled. These checks don't really belong in ice_ptp_hw.c, and
make more sense as part of the ice_common.c file. We already have
ice_is_gps_in_netlist() in ice_common.c which is doing a similar check.
Move the functions into ice_common.c and rename them to have the similar
postfix of "in_netlist()" to be more expressive of what they are actually
checking.
This also makes the ice_find_netlist_node only called from within
ice_common.c, so its safe to mark it static and stop declaring it in the
ice_common.h header as well.

assigning them to the active VFs.
Not doing so may cause discrepancies that ultimately may cause some VFs to

Older firmware does not support the TPID setting so check for
proper support.
Remove the unused BNXT_VF_QOS flag.

The use of hwmon_device_register_with_groups() is deprecated.
Modified the driver to use hwmon_device_register_with_info().
Driver currently exports only temp1_input through hwmon sysfs
interface. But FW has been modified to report more threshold
temperatures and driver want to report them through the
hwmon interface.

Driver currently does hwmon device register and unregister
in open and close() respectively. As a result, user will not
be able to query hwmon temperature when interface is in
ifdown state.
Enhance it by moving the hwmon register/unregister to the
probe/remove functions.

The main changes are the additional thermal thresholds in
hwrm_temp_monitor_query_output and the new async event to
report thermal errors.
