We currently have two forms of operations - small ops and "full" ops
(or just ops). The former does not have pointers for some of the less
commonly used features (namely dump start/done and policy).
The "full" ops, however, still don't contain all the necessary
information. In particular the policy is per command ID, while
do and dump often accept different attributes. It's also not
possible to define different pre_doit and post_doit callbacks
for different commands within the family.
At the same time a lot of commands do not support dumping and
therefore all the dump-related information is wasted space.
Create a new command representation which can hold info about
a do implementation or a dump implementation, but not both at
the same time.
Use this new representation on the command execution path
(genl_family_rcv_msg) as we either run a do or a dump and
don't have to create a "full" op there.

The code at the top of ctrl_dumppolicy() dumps mappings between
ops and policies. It supports dumping both the entire family and
single op if dump is filtered. But both of those cases are handled
inside a loop, which makes the logic harder to follow and change.
Refactor to split the two cases more clearly.

Add PM handlers for System suspend/resume.
As DMA driver doesn't yet support suspend/resume we free up
the DMA channels at suspend and acquire and initialize them
at resume.
Move the init/free dma calls to ndo_open/close() hooks so
it is symmetric and easier to invoke from suspend/resume handler.

Simplify the code logic of handling the quirk of FEC_QUIRK_HAS_RACC.
If a SoC has the RACC quirk, the driver will enable the 16bit shift
by default in the probe function for a better performance.
This patch handles the logic in one place to make the logic simple
and clean. The patch optimizes the fec_enet_xdp_get_tx_queue function
according to Paolo Abeni's comments, and it also exludes the SoCs that
require to do frame swap from XDP support.

HINIC has a mailbox for PF-VF communication and the VF driver
could send port control command to PF driver via mailbox.
The control command only can be set to register in PF,
so add support in PF driver for VF PMD driver control
command when VF PMD driver work with linux PF driver.
Then, no need to add handlers to nic_vf_cmd_msg_handler[],
because the host driver just forwards it to the firmware.
Actually the firmware works on a coprocessor MGMT_CPU(inside the NIC)
which will recv and deal with these commands.

net: ipa: support more endpoints
This series adds support for more than 32 IPA endpoints. To do
this, five registers whose bits represent endpoint state are
replicated as needed to represent endpoints beyond 32. For existing
platforms, the number of endpoints is never greater than 32, so
there is just one of each register. IPA v5.0+ supports more than
that though; these changes prepare the code for that.
Beyond that, the IPA fields that represent endpoints in a 32-bit
bitmask are updated to support an arbitrary number of these endpoint
registers. (There is one exception, explained in patch 7.)
The first two patches are some sort of unrelated cleanups, making
use of a helper function introduced recently.
The third and fourth use parameterized functions to determine the
register offset for registers that represent endpoints.
The last five convert fields representing endpoints to allow more
than 32 endpoints to be represented.
Since v1, I have implemented Jakub's suggestions:
- Don't print a message on (bitmap) memory allocation failure
- Do not do "mass null checks" when allocating bitmaps
- Rework some code to ensure error path is sane

Prior to IPA v5.0, there could be no more than 32 endpoints.
A filter table begins with a bitmap indicating which endpoints have
a filter defined. That bitmap is currently assumed to fit in a
32-bit value.
Starting with IPA v5.0, more than 32 endpoints are supported, so
it's conceivable that a TX endpoint has an ID that exceeds 32.
Increase the size of the field representing endpoints that support
filtering to 64 bits. Rename the bitmap field "filtered".
Unlike other similar fields, we do not use an (arbitrarily long)
Linux bitmap for this purpose. The reason is that if a filter table
ever *did* need to support more than 64 TX endpoints, its format
would change in ways we can't anticipate.
Have ipa_endpoint_init() return a negative errno rather than a mask
that indicates which endpoints support filtering, and have that
function assign the "filtered" field directly.

IPA v5.0 supports more than 32 endpoints, so we will be unable to
represent endpoints defined in the configuration data with a 32-bit
value. To prepare for that, convert the field in the IPA structure
representing defined endpoints to be a Linux bitmap.
Convert loops based on that field into for_each_set_bit() calls over
the new bitmap. Note that the loop in ipa_endpoint_config() still
assumes there are 32 or fewer endpoints (when comparing against the
available endpoint bit mask); that assumption goes away in the next
patch.

Starting with IPA v5.0, a single IPA instance can have more than 32
endpoints defined. To handle this, each register that holds a
bitmap of IPA endpoints is replicated as needed to represent the
available endpoints.
To prepare for this, registers that represent endpoint IDs in a bit
mask will be defined to have a parameter, with a stride value of 4
bytes. The first 32 endpoints are represented in the first 32-bit
register, then the next (up to) 32 endpoints at an offset 4 bytes
higher. When accessing such a register, the endpoint ID divided
by 32 determines the offset, and the endpoint ID modulo 32 defines
the endpoint's bit position within the register.
The first two registers we'll update for this are STATE_AGGR_ACTIVE
and AGGR_FORCE_CLOSE.
Until more than 32 endpoints are supported, this change has no
practical effect.

Recently ipa_table_mem() was added as a way to look up one of 8
possible memory regions by indicating whether it was a filter or
route table, hashed or not, and IPv6 or not.
We can simplify the interface to ipa_table_init_add() by passing two
flags to it instead of the opcode and both hashed and non-hashed
memory region IDs. The "filter" and "ipv6" flags are sufficient to
determine the opcode to use, and with ipa_table_mem() can look up
the correct memory region as well.
It's possible to not have hashed tables, but we already verify the
number of entries in a filter or routing table is nonzero. Stop
assuming a hashed table entry exists in ipa_table_init_add().

Joe Damato adds tracepoint information to i40e_napi_poll to expose helpful
debug information for users who'd like to get a better understanding of
how their NIC is performing as they adjust various parameters and tuning
knobs.
Note: this does not touch any XDP related code paths. This
tracepoint will only work when not using XDP. Care has been taken to avoid
changing control flow in i40e_napi_poll with this change.
Alicja adds error messaging for unsupported duplex settings for i40e.
Ye Xingchen replaces use of __FUNCTION__ with __func__ for iavf.
Bartosz changes tense of device removal message to be more clear on the
action for iavf.
* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
iavf: Change information about device removal in dmesg
iavf: Replace __FUNCTION__ with __func__
i40e: Add appropriate error message logged for incorrect duplex setting
i40e: Add i40e_napi_poll tracepoint
i40e: Record number of RXes cleaned during NAPI
i40e: Record number TXes cleaned during NAPI
i40e: Store the irq number in i40e_q_vector

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:
drivers/net/hamradio/baycom_epp.c:1119:25: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = baycom_send_packet,
^~~~~~~~~~~~~~~~~~
1 error generated.
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of baycom_send_packet()
to match the prototype's to resolve the warning and CFI failure.

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.
In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.
While at it, include the corresponding header file (<linux/kstrtox.h>).

====================
net: fix netdev to devlink_port linkage and expose to user
Currently, the info about linkage from netdev to the related
devlink_port instance is done using ndo_get_devlink_port().
This is not sufficient, as it is up to the driver to implement it and
some of them don't do that. Also it leads to a lot of unnecessary
boilerplate code in all the drivers.
Instead of that, introduce a possibility for driver to expose this
relationship by new SET_NETDEV_DEVLINK_PORT macro which stores it into
dev->devlink_port. It is ensured by the driver init/fini flows that
the devlink_port pointer does not change during the netdev lifetime.
Devlink port is always registered before netdev register and
unregistered after netdev unregister.
Benefit from this linkage setup and remove explicit calls from driver
to devlink_port_type_eth_set() and clear(). Many of the driver
didn't use it correctly anyway. Let the devlink.c to track associated
netdev events and adjust type and type pointer accordingly. Also
use this events to to keep track on ifname change and remove RTNL lock
taking from devlink_nl_port_fill().
Finally, remove the ndo_get_devlink_port() ndo which is no longer used
and expose devlink_port handle as a new netdev netlink attribute to the
user. That way, during the ifname->devlink_port lookup, userspace app
does not have to dump whole devlink port list and instead it can just
do a simple RTM_GETLINK query.
