From: Luca Coelho <[email protected]>
Hi,
Here's the seventh set of patches intended for v5.12. It's the usual
development, new features, cleanups and bugfixes.
The changes are:
* Support new scan config FW API;
* Some more CSA fixes;
* Support for RF interference mitigation (RFI);
* Improvements in the NVM flows;
* Some other small fixes, clean-ups and improvements.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

2.30.0
From: Gregory Greenman <[email protected]>
RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.
This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
that driver sent).

2.30.0
From: Abhishek Naik <[email protected]>
Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load
NVM to nic func fails and NVM is not loaded to fw properly, then fw may
behave badly and lead to some strange issue. This commit will analyze
return value and if load NVM to nic has failed, then the error code is
sent to the previous func, which will trigger WRT log collection.
iwl_fw_dbg_error_collect() func collects dump only if tri type is
FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails
trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to
collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

From: Shaul Triebitz <[email protected]>

whether *we* support ack-enabled.
So what should be checked is our *own* capability and not
the *peer's* capability.

From: Emmanuel Grumbach <[email protected]>
We don't need the NVM until fairly late in the flow and
since this flow will be split soon, get the NVM later to
unite it with the parts that really need it.
Gather all what needs the NVM into a function.
