A previous patch added wcn36xx_smd_config_bss_v0() this patch converts the

This patch updates wcn36xx_smd_config_bss_v1() to update on internally
derived parameters only, specifically making use of STA v1 wrapper routines
previously added.
Once done we no longer need to pass a struct wcn36xx_hal_config_bss_req_msg
which gives us options in later patches to eliminate the kzalloc() in
wcn36xx_smd_config_bss entirely.

In order to pass VHT parameters to wcn3680 we need to use a super-set of
the V1 data-structures with additional VHT parameters tacked on.
This patch adds the additional fields to the STA and BSS parameter
structures.
Since neither wcn3620 nor wcn3660 support VHT the size of the passed
message is fixed to the previous message length. Subsequent changes will
differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger

usb_kill_anchored_urbs()
Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().

net: ethernet: ti: ale: add static configuration
As existing, as newly introduced CPSW ALE versions have differences in

recent AM65x/J721E/J7200 and future AM64x SoCs, which supports more
features like: auto-aging, classifiers, Link aggregation, additional HW

The existing ALE configuration interface is not practical in terms of

ALE configuration is static and fixed for SoC (or set of SoC), It is
reasonable to add support for static ALE configurations inside ALE module.
This series introduces static ALE configuration table for different ALE
variants and provides option for consumers to select required ALE
configuration by providing ALE const char *dev_id identifier (Patch 2).
And all existing driver have been switched to use new approach (Patches 3-6).
After this ALE HW auto-ageing feature can be enabled for AM65x CPSW ALE
variant (Patch 7).
Finally, Patches 8-9 introduces tables to describe the ALE VLAN entries
fields as the ALE VLAN entries are too much differ between different TI
CPSW ALE versions. So, handling them using flags, defines and get/set
functions are became over-complicated.

DSA tag_8021q cleanup
This small series tries to consolidate the VLAN handling in DSA a little

This reverts commit 314f76d7a68bab0516aa52877944e6aacfa0fc3f.
Citing that commit message, the call graph was:
dsa_slave_vlan_rx_add_vid dsa_port_setup_8021q_tagging

| +-------------+
| |
v v
dsa_port_vid_add dsa_slave_port_obj_add
| |
+-------+ +-------+
| |
v v
dsa_port_vlan_add
Now that tag_8021q has its own ops structure, it no longer relies on
dsa_port_vid_add, and therefore on the dsa_switch_ops to install its
VLANs.
So dsa_port_vid_add now only has one single caller. So we can simplify
the call graph to what it was before, aka:
dsa_slave_vlan_rx_add_vid dsa_slave_port_obj_add
| |
+-------+ +-------+

While working on another tag_8021q driver implementation, some things
became apparent:
- It is not mandatory for a DSA driver to offload the tag_8021q VLANs by
using the VLAN table per se. For example, it can add custom TCAM rules
that simply encapsulate RX traffic, and redirect & decapsulate rules
for TX traffic. For such a driver, it makes no sense to receive the
tag_8021q configuration through the same callback as it receives the
VLAN configuration from the bridge and the 8021q modules.
- Currently, sja1105 (the only tag_8021q user) sets a
priv->expect_dsa_8021q variable to distinguish between the bridge
calling, and tag_8021q calling. That can be improved, to say the
least.
- The crosschip bridging operations are, in fact, stateful already. The
list of crosschip_links must be kept by the caller and passed to the
relevant tag_8021q functions.
So it would be nice if the tag_8021q configuration was more
self-contained. This patch attempts to do that.
Create a struct dsa_8021q_context which encapsulates a struct
dsa_switch, and has 2 function pointers for adding and deleting a VLAN.
These will replace the previous channel to the driver, which was through
the .port_vlan_add and .port_vlan_del callbacks of dsa_switch_ops.
Also put the list of crosschip_links into this dsa_8021q_context.
Drivers that don't support cross-chip bridging can simply omit to
initialize this list, as long as they dont call any cross-chip function.
The sja1105_vlan_add and sja1105_vlan_del functions are refactored into
a smaller sja1105_vlan_add_one, which now has 2 entry points:
- sja1105_vlan_add, from struct dsa_switch_ops
- sja1105_dsa_8021q_vlan_add, from the tag_8021q ops
But even this change is fairly trivial. It just reflects the fact that
for sja1105, the VLANs from these 2 channels end up in the same hardware
table. However that is not necessarily true in the general sense (and
that's the reason for making this change).
The rest of the patch is mostly plain refactoring of "ds" -> "ctx". The
dsa_8021q_context structure needs to be propagated because adding a VLAN
is now done through the ops function pointers inside of it.

There is no point in calling dsa_port_setup_8021q_tagging for each
individual port. Additionally, it will become more difficult to do that
when we'll have a context structure to tag_8021q (next patch). So
refactor this now.

Remove the tx_queue->handle_tso function pointer, and just use
tx_queue->tso_version to decide which function to call, thus removing
an indirect call from the fast path.
Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired
tx_queue->tso_version before calling it.
In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by
setting tx_queue->tso_version to 0, which will cause the TX path to
use the GSO-based fallback.

Each MDB entry is encoded in a nested netlink attribute called
'MDBA_MDB_ENTRY'. In turn, this attribute contains another nested
attributed called 'MDBA_MDB_ENTRY_INFO', which encodes a single port
group entry within the MDB entry.
The cited commit added the ability to restart a dump from a specific
port group entry. However, on failure to add a port group entry to the
dump the entire MDB entry (stored in 'nest2') is removed, resulting in
missing port group entries.
Fix this by finalizing the MDB entry with the partial list of already
encoded port group entries.
