46837be5af net: ethtool: rss: add notifications 
In preparation for RSS_SET handling in ethnl introduce Netlink
notifications for RSS. Only cover modifications, not creation
and not removal of a context, because the latter may deserve
a different notification type. We should cross that bridge
when we add the support for context add / remove via Netlink.

3073947de3 net: ethtool: copy req_info from SET to NTF 
Copy information parsed for SET with .req_parse to NTF handling
and therefore the GET-equivalent that it ends up executing.
This way if the SET was on a sub-object (like RSS context)
the notification will also be appropriately scoped.

Also copy the phy_index, Maxime suggests this will help PLCA
commands generate accurate notifications as well.

f9dc3e52d8 net: ethtool: remove the data argument from ethtool_notify() 
ethtool_notify() takes a const void *data argument, which presumably
was intended to pass information from the call site to the subcommand
handler. This argument currently has no users.

Expecting the data to be subcommand-specific has two complications.

Complication #1 is that its not plumbed thru any of the standardized
callbacks. It gets propagated to ethnl_default_notify() where it
remains unused. Coming from the ethnl_default_set_doit() side we pass
in NULL, because how could we have a command specific attribute in
a generic handler.

Complication #2 is that we expect the ethtool_notify() callers to
know what attribute type to pass in. Again, the data pointer is
untyped.

RSS will need to pass the context ID to the notifications.
I think it's a better design if the "subcommand" exports its own
typed interface and constructs the appropriate argument struct
(which will be req_info). Remove the unused data argument from
ethtool_notify() but retain it in a new internal helper which
subcommands can use to build a typed interface.

963781bdfe net: ethtool: call .parse_request for SET handlers 
In preparation for using req_info to carry parameters between SET
and NTF - call .parse_request during ethnl_default_set_doit().

The main question here is whether .parse_request is intended to be
GET-specific. Originally the SET handling was delegated to each subcommand
directly - ethnl_default_set_doit() and .set callbacks in ethnl_request_ops
did not exist. Looking at existing users does not shed much light, all
of the following subcommands use .parse_request but have no SET handler
(and no NTF):

  net/ethtool/eeprom.c
  net/ethtool/rss.c
  net/ethtool/stats.c
  net/ethtool/strset.c
  net/ethtool/tsinfo.c

There's only one which does have a SET:

  net/ethtool/pause.c

where .parse_request handling is used to select which statistics to query.
Not relevant for SET but also harmless.

Going back to RSS (which doesn't have SET today) .parse_request parses
the rss_context ID. Using the req_info struct to pass the context ID
from SET to NTF will be very useful.

Switch to ethnl_default_parse(), effectively adding the .parse_request
for SET handlers.

e3ad987e9d wifi: iwlwifi: dvm: fix potential overflow in rs_fill_link_cmd() 
The 'index' variable in the rs_fill_link_cmd() function can reach
LINK_QUAL_MAX_RETRY_NUM during the execution of the inner loop. This
variable is used as an index for the lq_cmd->rs_table array, which has a
size of LINK_QUAL_MAX_RETRY_NUM, without proper validation.

Modify the condition of the inner loop to ensure that the 'index' variable
does not exceed LINK_QUAL_MAX_RETRY_NUM - 1, thereby preventing any
potential overflow issues.

0cdb8ff6eb wifi: iwlwifi: mld: don't exit EMLSR when we shouldn't 
There is a requirement to exit EMLSR if there wasn't enough throughput
in the secondary link.
This is checked in check_tpt_wk, which runs every 5 seconds in a high
throughput scenario (when the throughput blocker isn't set)

It can happen that this worker is running immediately after we entered
EMLSR, and in that case the secondary link didn't have a chance to have
throughput. In that case we will exit EMLSR for no good reason.

Fix this by tracking the time we entered EMLSR, and in the worker make
sure that 5 seconds passed from when we entered EMLSR. If not, don't
check the secondary link throughput.

9748ad82a9 wifi: iwlwifi: defer MLO scan after link activation 
Doing a scan right after link activation can be less reliable
than at other times, as the firmware is still busy trying to
catch beacons from the just activated link, etc. In case a new
MLO scan request comes in, defer it for a few seconds after a
link activation.

1cc04e196a wifi: iwlwifi: mld: remove special FW error resume handling 
The (applicable) firmware versions will send an error interrupt as
part of the resume process, so there's no need now to check for it
explicitly. Simplify the code. This also fixes an issue where any
dump taken during the resume isn't able to do the reset handshake
as part of the dump (since interrupts are disabled) and then there
isn't all the correct data and we get more errors later.
