Split types and pure function declarations from page_pool.h
and add them in page_page/types.h, so that C sources can
include page_pool.h and headers should generally only include
page_pool/types.h as suggested by jakub.
Rename page_pool.h to page_pool/helpers.h to have both in
one place.

netdev_err() for platform_get_irq()
There is no possible for platform_get_irq() to return 0
and the return value of platform_get_irq() is more sensible
to show the error reason.
And there is no need to call the netdev_err() function directly to print
a custom message when handling an error from platform_get_irq() function as
it is going to display an appropriate error message in case of a failure.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Once again, a busy development cycle, with lots of changes happening

changes.
This will make the future rust interactions with the driver core more

for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other

- cacheinfo improvements and updates

- documentation updates

not assume mac_header is set in macvlan_broadcast()"), let's introduce a
skb_vlan_eth_hdr() helper which can be used in TX-only code paths to get

skb_mac_header(skb).
We also consolidate the drivers that dereference skb->data to go through
this helper.

Devlink features were introduced to disallow devlink reload calls of
userspace before the devlink was fully initialized. The reason for this
workaround was the fact that devlink reload was originally called
without devlink instance lock held.
However, with recent changes that converted devlink reload to be
performed under devlink instance lock, this is redundant so remove
devlink features entirely.
Note that mlx5 used this to enable devlink reload conditionally only
when device didn't act as multi port slave. Move the multi port check
into mlx5_devlink_reload_down() callback alongside with the other
checks preventing the device from reload in certain states.

Currently, it used old rss size to get current tc mode. As a result, the
rss size is updated, but the tc mode is still configured based on the old
rss size.
So this patch fixes it by using the new rss size in both process.

Currently, the PF check the VF alive by the KEEP_ALVE
mailbox from VF. VF keep sending the mailbox per 2
seconds. Once PF lost the mailbox for more than 8
seconds, it will regards the VF is abnormal, and stop
notifying the state change to VF, include link state,
vf mac, reset, even though it receives the KEEP_ALIVE
mailbox again. It's inreasonable.
This patch fixes it. PF will record the state change which
need to notify VF when lost the VF's KEEP_ALIVE mailbox.
And notify VF when receive the mailbox again. Introduce a
new flag HCLGE_VPORT_STATE_INITED, used to distinguish the
case whether VF driver loaded or not. For VF will query
these states when initializing, so it's unnecessary to
notify it in this case.

Currently keep alive message between PF and VF may be lost and the VF is
unalive in PF. So the VF will not do reset during PF FLR reset process.
This would make the allocated interrupt resources of VF invalid and VF
would't receive or respond to PF any more.
So this patch adds VF interrupts re-initialization during VF FLR for VF
recovery in above cases.

The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.
In order to factorize code, make devlink_nl_info_fill() add the driver
name attribute.
Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.
