When offloading a TC encap action, the action information for the
hardware might not be "ready": if there's currently no neighbour entry
available for the destination address, we can't construct the Ethernet
header to prepend to the packet. In this case, we still offload the
flow rule, but with its action-set-list ID pointing at a "fallback"
action which simply delivers the packet to its default destination (as
though no flow rule had matched), thus allowing software TC to handle
it. Later, when we receive a neighbouring update that allows us to
construct the encap header, the rule will become "ready" and we will
update its action-set-list ID in hardware to point at the actual
offloaded actions.
This patch sets up these fallback ASLs, but does not yet use them.

Enable more than 32 IRQs by removing the u32 bit mask in
iavf_irq_enable_queues(). There is no need for the mask as there are no
callers that select individual IRQs through the bitmask. Also, if the PF
allocates more than 32 IRQs, this mask will prevent us from using all of
them.
Modify the comment in iavf_register.h to show that the maximum number
allowed for the IRQ index is 63 as per the iAVF standard 1.0 [1].

In case user wants to configure the SFs, for example: to use only vdpa
functionality, he needs to fully probe a SF, configure what he wants,
and afterward reload the SF.
In order to save the time of the reload, local SFs will probe without
any auxiliary sub-device, so that the SFs can be configured prior to
its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

mlx5_cmd_init_hca() is taking ~0.2 seconds. In case of a user who
desire to disable some of the SF aux devices, and with large scale-1K
SFs for example, this user will waste more than 3 minutes on
mlx5_cmd_init_hca() which isn't needed at this stage.
Downstream patch will change SFs which are probe over the E-switch,
local SFs, to be probed without any aux dev. In order to support this,
split function_setup() to avoid executing mlx5_cmd_init_hca().

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Both ath10k platform drivers return zero unconditionally in their remove
callback, so they can be trivially converted to use .remove_new().
Also fix on of the more offending whitespace issues in the definition
of ath10k_snoc_driver.

The timestamp descriptors were intended to act cyclically. Descriptors
from index 0 through gq->ring_size - 1 contain actual information, and
the last index (gq->ring_size) should have LINKFIX to indicate
the first index 0 descriptor. However, the LINKFIX value is missing,
causing the timestamp feature to stop after all descriptors are used.
To resolve this issue, set the LINKFIX to the timestamp descritors.

Recent iOS releases support CDC NCM encapsulation on RX. This mode is
the default on macOS and Windows. In this mode, an iOS device may include
one or more Ethernet frames inside a single URB.
Freshly booted iOS devices start in legacy mode, but are put into
NCM mode by the official Apple driver. When reconnecting such a device
from a macOS/Windows machine to a Linux host, the device stays in
NCM mode, making it unusable with the legacy ipheth driver code.
To correctly support such a device, the driver has to either support
the NCM mode too, or put the device back into legacy mode.
To match the behaviour of the macOS/Windows driver, and since there
is no documented control command to revert to legacy mode, implement
NCM support. The device is attempted to be put into NCM mode by default,
and falls back to legacy mode if the attempt fails.

====================
mlx5-updates-2023-06-06
1) Support 4 ports VF LAG, part 2/2
2) Few extra trivial cleanup patches
Shay Drory Says:
================
Support 4 ports VF LAG, part 2/2
This series continues the series[1] "Support 4 ports VF LAG, part1/2".
This series adds support for 4 ports VF LAG (single FDB E-Switch).
This series of patches refactoring LAG code that make assumptions
about VF LAG supporting only two ports and then enable 4 ports VF LAG.
Patch 1:
- Fix for ib rep code
Patches 2-5:
- Refactors LAG layer.
Patches 6-7:
- Block LAG types which doesn't support 4 ports.
Patch 8:
- Enable 4 ports VF LAG.
This series specifically allows HCAs with 4 ports to create a VF LAG
with only 4 ports. It is not possible to create a VF LAG with 2 or 3
ports using HCAs that have 4 ports.
Currently, the Merged E-Switch feature only supports HCAs with 2 ports.
However, upcoming patches will introduce support for HCAs with 4 ports.
In order to activate VF LAG a user can execute:
devlink dev eswitch set pci/0000:08:00.0 mode switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev
devlink dev eswitch set pci/0000:08:00.2 mode switchdev
devlink dev eswitch set pci/0000:08:00.3 mode switchdev
ip link add name bond0 type bond
ip link set dev bond0 type bond mode 802.3ad
ip link set dev eth2 master bond0
ip link set dev eth3 master bond0
ip link set dev eth4 master bond0
ip link set dev eth5 master bond0
Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0
pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.
User can verify LAG state and type via debugfs:
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/state
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/type

Use pcs-lynx's check rather than our own when determining if the device
is available. This fixes a bug where the reference gained by
of_parse_phandle() is not dropped if the device is not available.

Check that the fwnode is marked as available prior to trying to lookup
the PCS device, and return -ENODEV if unavailable. Document the return
codes from lynx_pcs_create_fwnode().

Change lynx_pcs_create() to return an error-pointer on failure to
allocate memory, rather than returning NULL. This allows the removal
of the conversion in lynx_pcs_create_fwnode() and
lynx_pcs_create_mdiodev().

We no longer need to export lynx_pcs_create() for drivers to use as we
now have all the functionality we need in the two new creation helpers.
Remove the export and prototype, and make it static.
