====================
mlxsw: Refactor parsing configuration
The Spectrum ASIC has a configurable limit on how deep into the packet
it parses. By default, the limit is 96 bytes.
There are several cases where this parsing depth is not enough and there
is a need to increase it: Decapsulation of VxLAN packets and
timestamping of PTP packets.
Currently, parsing depth API is maintained as part of VxLAN module,
because the MPRS register which configures parsing depth also configures
UDP destination port number used for VxLAN encapsulation and
decapsulation.
However, in addition to two above mentioned users of this API, the
multipath hash code also needs to invoke it in order to correctly hash
based on inner fields of IPv6-in-IPv6 packets.
Upcoming support for IPv6-in-IPv6 tunneling will add another user, as
without increasing the parsing depth such packets cannot be properly
decapsulated.
Therefore, this patchset refactors the parsing configuration API and
moves it out of the VxLAN module to the main driver code.
Tested using existing selftests.
Patch set overview:
Patch #1 adds the new parsing configuration infrastructure.
Patch #2 converts existing users to the new infrastructure.
Patch #3 deletes the old infrastructure.
Patch #4 calls the new infrastructure from the multipath hash code.

Commit 01848e05f8bb ("mlxsw: spectrum_router: Add support for inner
layer 3 multipath hash policy") and commit daeabf89eb89 ("mlxsw:
spectrum_router: Add support for custom multipath hash policy") added
support for multipath hash policies where the hash is calculated based
on inner packet fields.
For IPv6-in-IPv6 packets, the default parsing depth (96 bytes) is not
enough when these policies are used.
Therefore, for such cases, call the new API to increase / decrease the
parsing depth as necessary. Care is taken to ensure the API is not
called multiple times.

is a need to increase it. Currently, increasing parsing depth is
maintained as part of VxLAN module, because the MPRS register which
configures parsing depth also configures UDP destination port number
used for VxLAN encapsulation and decapsulation.
Add an API for increasing parsing depth as part of spectrum.c code, so
that it will be possible to use it from other modules. In addition, add
an API for setting UDP destination port and protect it using a dedicated
lock for saving parsing configurations. The lock is needed as not all
the callers hold RTNL lock.
Maintain a counter for increased parsing depth consumers. For first
consumer subscription, increase the parsing depth and for last consumer
unsubscription, set parsing depth to default value.

Otherthan setting action as RSS in NPC MCAM entry, RSS flowkey
algorithm index also needs to be set. Otherwise whatever algorithm
is defined at flowkey index '0' will be considered by HW and pkt
flows will be distributed as such.

Whenever user changes interface MAC address both default DMAC based
MCAM rule and VLAN offload (for strip) rules are updated with new
MAC address. To update or install VLAN offload rule PF driver needs
interface's receive channel info, which is retrieved from admin
function at the time of NIXLF initialization.
If user changes MAC address before interface is UP, VLAN offload rule
installation will fail and throw error as receive channel is not valid.
To avoid this, skip VLAN offload rule installation if netdev is not UP.
This rule will anyway be reinslatted as part of open() call.

for programmable channels of a block must be multiple
of number of channels of that block. This condition
is not met for SDP base channel currently. Hence this
patch ensures all the base channel numbers of all

the blocks. Also instead of hardcoding SDP number
of channels the same is read from the NIX_AF_CONST1

ipa_clock_disable() -> ipa_power_disable()
ipa_clock_rate() -> ipa_core_clock_rate()
ipa_clock_init() -> ipa_power_init()
ipa_clock_exit() -> ipa_power_exit()
Rename the ipa_clock structure to be ipa_power. Rename all
variables and fields using that structure type "power" rather
than "clock".
Rename the ipa_clock_data structure to be ipa_power_data, and more

previously represented things related to the "IPA clock".

Use runtime power management autosuspend.
Up until this point, we only suspended the IPA hardware for system
suspend; now we'll suspend it aggressively using runtime power
management, setting the initial autosuspend delay to half a second
of inactivity.
Replace pm_runtime_put() calls with pm_runtime_put_autosuspend(),
call pm_runtime_mark_last_busy() before each of those. In places
where we're shutting things down, or decrementing power references
for errors, use pm_runtime_put_noidle() instead.
Finally, remove ipa_runtime_idle(), so the ->runtime_suspend
callback will occur if idle.

The rtw_pci_init_rx_ring function is only ever called with a fixed
constant or RTK_MAX_RX_DESC_NUM for the "len" argument. Since this
constant is defined as 512, the "if (len > TRX_BD_IDX_MASK)" check
can never happen (TRX_BD_IDX_MASK is defined as GENMASK(11, 0) or in
other words as 4095).
So, remove this check.
The true motivation for this patch is to silence a false Coverity
warning.

There will be crazy numbers of interrupts triggered by 8188cu and
8192cu module, around 8000~10000 interrupts per second, on the usb
host controller. Compare with the vendor driver source code, it's
mapping to the configuration CONFIG_USB_INTERRUPT_IN_PIPE and it is
disabled by default.
Since the interrupt transfer is neither used for TX/RX nor H2C
commands. Disable it to avoid the excessive amount of interrupts
for the 8188cu and 8192cu module which I only have for verification.
