The ice driver uses an array of structures which link an info name with
a function that formats the associated version data into a string.
All existing format functions simply format already captured static data
from the driver hw structure. Future changes will introduce format
functions for reporting the versions of flash sections stored but not
yet applied. This type of version data is not stored as a member of the
hw structure. This is because (a) it might not yet exist in the case
there is no pending flash update, and (b) even if it does, it might
change such as if an update is canceled or replaced by a new update
before finalizing.
We could simply have each format function gather its own data upon being
called. However, in some cases the raw binary version data is
a combination of multiple different reported fields. Additionally, the
current interface doesn't have a way for the function to indicate that
the version doesn't exist.
Refactor this function interface to take a new ice_info_ctx structure
instead of the buffer pointer and length. This context structure allows
for future extensions to pre-gather version data that is stored within
the context struct instead of the hw struct.
Allocate this context structure initially at the start of
ice_devlink_info_get. We use dynamic allocation instead of a local stack
variable in order to avoid using too much kernel stack once we extend it
with additional data structures.
Modify the main loop that drives the info reporting so that the version
buffer string is always cleared between each format. Explicitly check
that the format function actually filled in a version string of non-zero
length. If the string is not provided, simply skip this version without
reporting an error. This allows for introducing format functions of
versions which may or may not be present, such as the version of
a pending update that has not yet been activated.

The ice_nvm_info structure has become somewhat of a dumping ground for
all of the fields related to flash version. It holds the NVM version and
EETRACK id, the OptionROM info structure, the flash size, the ShadowRAM
size, and more.
A future change is going to add the ability to read the NVM version and
EETRACK ID from the inactive NVM bank. To make this simpler, it is
useful to have these NVM version info fields extracted to their own
structure.
Rename ice_nvm_info into ice_flash_info, and create a separate
ice_nvm_info structure that will contain the eetrack and NVM map
version. Move the netlist_ver structure into ice_flash_info and rename it
ice_netlist_info for consistency.
Modify the static ice_get_orom_ver_info to take the option rom structure
as a pointer. This makes it more obvious what portion of the hw struct
is being modified. Do the same for ice_get_netlist_ver_info.
Introduce a new ice_get_nvm_ver_info function, which will be similar to
ice_get_orom_ver_info and ice_get_netlist_ver_info, used to keep the NVM
version extraction code co-located.

When erasing, notify userspace of how long we will potentially take to
erase a module. Doing so allows userspace to report the timeout, giving
a clear indication of the upper time bound of the operation.
Since we're re-using the erase timeout value, make it a macro rather
than a magic number.

When a change of memory map occurs, the hardware resources are destroyed
and then re-created again with the new memory map. In such case, we need
to restore the hardware available and used indices. The driver failed to
restore the used index which is added here.
Also, since the driver also fails to reset the available and used
indices upon device reset, fix this here to avoid regression caused by
the fact that used index may not be zero upon device reset.

When Rx queues are configured during module init, NAPI is enabled
while the Rx queue lock is held. However, since softirqs are not
disabled, it is possible that and IRQ would fire and call
iwl_pcie_rx_handle() which would also try to acquire the Rx lock.
Prevent this by disabling softirqs during Rx queue configuration,
as part of module init flow.

We should only allow PPAG to be enabled by OEMs that are in the
approved list. In order to do this, we need to compare the system
vendor string retrieved from SMBIOS to a list maintained in the
driver. If the vendor string is not in the list, we don't allow PPAG
to be used.
For now the list is empty, but entries will be added to it
individually, in subsequent patches.

In struct iwl_tx_cmd, there's no risk (as Arnd implied) that we
might access this as an array, as it's really not an array and
cannot be - there's only a single 802.11 header per frame. The
only reason for this member is for being able to access it a
bit more nicely.
On the other hand, this structure is used as a sub-struct in a
few places, and then some compilers (e.g. clang with certain
options) complain as you shouldn't have structs with variable-
length fields embedded in other structs.

When we check the length, we only check that the advertised
data length fits into the data we have, but currently not
that it actually matches correctly.
This should be harmless, but if the first two bytes are zero,
then the iwl_rx_packet_payload_len() ends up negative, and
that might later cause issues if unsigned variables are used,
as this is not something that's normally expected.
Change the validation here to precisely validate the lengths
match, to avoid such issues.

In roaming flows and during reassociation, its possible that data frames
such as EAPOLs for 4 way handshake/ 802.1x authentication are initially set
to higher MCS rate. Though these are pruned down to a lower legacy rate
before sending to the FW, driver also emits a kernel warning - intended for
non-data frames. Add checks to avoid such warnings for data frames, while
also enhancing the debug data printed.

While disconnecting from the AP due to bad channel switch
params (e.g. too long Tx block), do not send the firmware
'CSA abort' before disconnecting. That causes canceling the
immediate quiet and can cause transmitting data before the
disconnection happens.

D3_CONFIG_CMD and D0I3_END_CMD should be the last\first
command upon suspend\resume correspondingly, otherwise,
FW will raise an assert (0x342).
There are firmware notifications that cause the driver to
send a command back to the firmware. If such a notification
is sent to the driver while the the driver prepares the
firmware for D3, operation, what is likely to happen is that
the handling of the notification will try to get the mutex
and will wait unil the driver finished configuring the
firmware for D3. Then the handling notification will get
the mutex and handle the notification which will lead to
the aforementioned ASSERT 342.
To avoid this, we need to prevent any command to be sent to
the firmware between the D3_CONFIG_CMD and the D0I3_END_CMD.
Check this in the utility layer that sends the host commands
and in the transport layer as well.
Flag the D3_CONFIG_CMD and the D0I3_END_CMD commands as
commands that must be sent even if the firmware has already
been configured for D3 operation.

When we want to stop TX'ing because we are suspending, we
have two options: either we check system_pm_mode or we
check the mvm's status that has a bit for the suspend
flow.
The latter is better because test_bit is atomic. Also
add a call to synchronize_net after we set the bit to
make sure that all the new Tx see the bit before we
actually complete the suspend flow.

Instead of pretending to have NAPI and then relying entirely on
interrupts anyway, properly implement NAPI and schedule the poll
when we get an interrupt, re-enabling the interrupt only after
the poll completed.

In the new api all the flush in the FW is done before we
get the response and in the response we only get the updated
read pointer and all queued packets don't get anymore rx_tx
per packet to free the queued packet, so driver needs to free
all queued packets on flushed queue at once after flush response.

If there are frequent CCA delays due to the extension channel
as detected by the firmware, and we're on 2.4 GHz, then handle
this by disconnecting (with a reconnect hint).
When we disconnect, we'll also update our capabilities to use
only 20 MHz on the next connection (if it's on 2.4 GHz) as to
avoid the use of the extension channel that has too much noise.

When restarting firmware with an ongoing scheduled scan, we
don't (and shouldn't) mark it as aborted as mac80211 will be
restarting it, and so no event should go out to userspace.
The appropriate comment regarding this wasn't moved to this
place, so add it.
However, we _do_ need to clean up our internal state, since
mac80211 will restart the scan, and we'll otherwise get to
the WARN_ON() a few lines below for no reason whatsoever.
