wireless-next patches for v6.9
The third "new features" pull request for v6.9. This is a quick
followup to send commit
04edb5dc68f4 ("wifi: ath12k: Fix uninitialized
use of ret in ath12k_mac_allocate()") to fix the ath12k clang warning
introduced in the previous pull request.
We also have support for QCA2066 in ath11k, several new features in
ath12k and few other changes in drivers. In stack it's mostly cleanup
and refactoring.
Major changes:
ath12k
* firmware-2.bin support
* support having multiple identical PCI devices (firmware needs to
have ATH12K_FW_FEATURE_MULTI_QRTR_ID)
* QCN9274: support split-PHY devices
* WCN7850: enable Power Save Mode in station mode
* WCN7850: P2P support
ath11k:
* QCA6390 & WCN6855: support 2 concurrent station interfaces
* QCA2066 support

====================
bnxt_en: Ntuple filter improvements
The current Ntuple filter implementation has a limitation on 5750X (P5)
and newer chips. The destination ring of the ntuple filter must be
a valid ring in the RSS indirection table. Ntuple filters may not work
if the RSS indirection table is modified by the user to only contain a
subset of the rings. If an ntuple filter is set to a ring destination
that is not in the RSS indirection table, the packet matching that
filter will be placed in a random ring instead of the specified
destination ring.
This series of patches will fix the problem by using a separate VNIC
for ntuple filters. The default VNIC will be dedicated for RSS and
so the indirection table can be setup in any way and will not affect
ntuple filters using the separate VNIC.
Quite a bit of refactoring is needed to do the the VNIC and RSS
context accounting in the first few patches. This is technically a
bug fix, but I think the changes are too big for -net.

that destination ring is also in the RSS indirection table.

wifi: wilc1000: revert reset line logic flip
This reverts commit
fcf690b0b47494df51d214db5c5a714a400b0257.
When using a wilc1000 chip over a spi bus, users can optionally define a
reset gpio and a chip enable gpio. The reset line of wilc1000 is active
low, so to hold the chip in reset, a low (physical) value must be applied.
The corresponding device tree binding documentation was introduced by
commit
f31ee3c0a555 ("wilc1000: Document enable-gpios and reset-gpios
properties") and correctly indicates that the reset line is an active-low
signal. The corresponding driver part, brought by commit
ec031ac4792c
("wilc1000: Add reset/enable GPIO support to SPI driver") was applying the
correct logic. But commit
fcf690b0b474 ("wifi: wilc1000: use correct
sequence of RESET for chip Power-UP/Down") eventually flipped this logic
and started misusing the gpiod APIs, applying an inverted logic when
powering up/down the chip (for example, setting the reset line to a logic
"1" during power up, which in fact asserts the reset line when device tree
describes the reset line as GPIO_ACTIVE_LOW). As a consequence, any
platform currently using the driver in SPI mode must use a faulty reset
line description in device tree, or else chip will be maintained in reset
and will not even allow to bring up the chip.
Fix reset line usage by inverting back the gpiod APIs usage, setting the
reset line to the logic value "0" when powering the chip, and the logic
value "1" when powering off the chip.

The issue here is that we managed to probe the GENET controller, the
mdio-bcm-unimac MDIO controller, but the PHY was still being held in a
probe deferral state because it depended upon a GPIO controller provider
not loaded yet. As soon as that provider is loaded however, the PHY
continues to probe, tries to disable the interrupts, and this causes a
MDIO transaction. That MDIO transaction requires I/O register accesses
within the GENET's larger block, and since its clocks are turned off,
the CPU gets a bus error signaled as a System Error.
The patch series takes the simplest approach of keeping the clocks
enabled just for the duration of the I/O accesses. This is also
beneficial to other drivers like bcmasp2 which make use of the same MDIO
controller driver.
Changes in v2:
- added missing ret assignment in the if (IS_ERR(priv->clk)) branch
- added Jacob's R-by tags
- corrected the commit ID being reverted in patch #3

net: mdio: mdio-bcm-unimac: Manage clock around I/O accesses
Up until now we have managed not to have the mdio-bcm-unimac manage its
clock except during probe and suspend/resume. This works most of the
time, except where it does not.
With a fully modular build, we can get into a situation whereby the
GENET driver is fully registered, and so is the mdio-bcm-unimac driver,
however the Ethernet PHY driver is not yet, because it depends on a
resource that is not yet available (e.g.: GPIO provider). In that state,
the network device is not usable yet, and so to conserve power, the
GENET driver will have turned off its "main" clock which feeds its MDIO
controller.
When the PHY driver finally probes however, we make an access to the PHY
registers to e.g.: disable interrupts, and this causes a bus error
within the MDIO controller space because the MDIO controller clock(s)
are turned off.
To remedy that, we manage the clock around all of the I/O accesses to
the hardware which are done exclusively during read, write and clock
divider configuration.
This ensures that the register space is accessible, and this also
ensures that there are not unnecessarily elevated reference counts
keeping the clocks active when the network device is administratively
turned off. It would be the case with the previous way of managing the
clock.

ip6mr: Simplify the allocation of slab caches in ip6_mr_init
Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.
And change cache name from 'ip6_mrt_cache' to 'mfc6_cache'.

net/dummy: Move stats allocation to core
With commit
34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core instead
of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Move dummy driver to leverage the core allocation.

tg3: copy only needed fields from userspace-provided EEE data
The current code overwrites fields in tp->eee with unchecked data from
edata, e.g. the bitmap with supported modes. ethtool properly returns
the received data from get_eee() call, but we have no guarantee that
other users of the ioctl set_eee() interface behave properly too.
Therefore copy only fields which are actually needed.

Merge branch 'net-constify-device_type'
Ricardo B. Marliere says:
====================
net: constify struct device_type usage
This is a simple and straight forward cleanup series that makes all device
types in the net subsystem constants. This has been possible since 2011 [1]
but not all occurrences were cleaned. I have been sweeping the tree to fix
them all.
I was not sure if I should send these squashed, but there are quite a few
changes so I decided to send them separately. Please let me know if that is
not desirable.
