The macros I40E_MDIO_CLAUSE22* and I40E_MDIO_CLAUSE45* are using I40E_MASK
together with the same values I40E_GLGEN_MSCA_STCODE_SHIFT and

Before Google adopted FQ for its production servers,
we had to ensure AF4 packets would get a higher share
than BE1 ones.

As discussed this week in Netconf 2023 in Paris, it is time
to upstream this for public use.

After this patch FQ can replace pfifo_fast, with the following
differences :

- FQ uses WRR instead of strict prio, to avoid starvation of
  low priority packets.

- We make sure each band/prio tracks its own usage against sch->limit.
  This was done to make sure flood of low priority packets would not
  prevent AF4 packets to be queued. Contributed by Willem.

- priomap can be changed, if needed (default value are the ones
  coming from pfifo_fast).

In this patch, we set default band weights so that :

- high prio (band=0) packets get 90% of the bandwidth
  if they compete with low prio (band=2) packets.

- high prio packets get 75% of the bandwidth
  if they compete with medium prio (band=1) packets.

Following patch in this series adds the possibility to tune
the per-band weights.

As we added many fields in 'struct fq_sched_data', we had
to make sure to have the first cache line read-mostly, and
avoid wasting precious cache lines.

More optimizations are possible but will be sent separately.

A bulk transfer of the USB may contain many packets. And, the total
number of the packets in the bulk transfer may be more than budget.

Originally, only budget packets would be handled by napi_gro_receive(),
and the other packets would be queued in the driver for next schedule.

This patch would break the loop about getting next bulk transfer, when
the budget is exhausted. That is, only the current bulk transfer would
be handled, and the other bulk transfers would be queued for next
schedule. Besides, the packets which are more than the budget in the
current bulk trasnfer would be still queued in the driver, as the
original method.

In addition, a bulk transfer wouldn't contain more than 400 packets, so
the check of queue length is unnecessary. Therefore, I replace it with
WARN_ON_ONCE().

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.

Newer versions of firmware will pre-reserve 1 VNIC for every possible
PF and VF function.  Update the driver logic to take this into account
when assigning VNICs to the VFs.  These pre-reserved VNICs for the
inactive VFs should be subtracted from the global pool before
assigning them to the active VFs.

Not doing so may cause discrepancies that ultimately may cause some VFs to
have insufficient VNICs to support features such as aRFS.

Add these missing settings in the .ndo_set_vf_vlan() method.
Older firmware does not support the TPID setting so check for
proper support.

Remove the unused BNXT_VF_QOS flag.

Newer FW will send a new async event when it detects that
the chip's temperature has crossed the configured threshold value.
The driver will now notify hwmon and will log a warning message.

Implement the sysfs attributes directly in the driver for
shutdown threshold temperature and pass an extra attribute group
to the hwmon core when registering the hwmon device.

HWRM_TEMP_MONITOR_QUERY response now indicates various
threshold temperatures. Expose these threshold temperatures
through the hwmon sysfs using this mapping:

hwmon_temp_max : bp->warn_thresh_temp
hwmon_temp_crit : bp->crit_thresh_temp
hwmon_temp_emergency : bp->fatal_thresh_temp

hwmon_temp_max_alarm : temp >= bp->warn_thresh_temp
hwmon_temp_crit_alarm : temp >= bp->crit_thresh_temp
hwmon_temp_emergency_alarm : temp >= bp->fatal_thresh_temp

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.
