From: Luca Coelho <[email protected]>
Hi,
Here's the second set of patches intended for v5.2. It's the usual
development, new features, cleanups and bugfixes.
The changes are:
* Continued work and bugfixes for the new debugging infra;
* Support for some new FW API versions;
* Some work to support new hardware;
* General bugfixes;
* Other cleanups;
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

From: Shaul Triebitz <[email protected]>
If number of channels in the driver is greater than
number of scan channels given by firmware TLV, do not
fail scan config, but adjust to firmware's number of channels.
This is helpful for supporting in driver new channels before
it being supported by firmware scan.

From: Luca Coelho <[email protected]>
Make sure the length of the ciphers we are copying never exceeds the
space we have for storing them. There is no risk of overcopying at
the moment, because we check n_params before, but this makes this
function safer in case someone changes something in the future.

2.20.1
From: Shahar S Matityahu <[email protected]>
In restart flow, the driver requests HW restart from mac80211
and then mac80211 uses a worker to do the restart flow. In that flow a
sync dump is performed. Instead, schedule the dump worker before
requesting HW restart from mac80211. This approach simplifies the
restart flow.
Also, it is neeeded in order to differentiate between the handling of SW
and HW errors in a future commit.

From: Ilan Peer <[email protected]>
Newer FWs use a new format of the SCAN_OFFLOAD_PROFILES_QUERY_RSP,
which now supports indicating match on an higher number of channels.
Modify the code to support both the old format and the newer one,
based on a FW TLV.

From: Johannes Berg <[email protected]>
The layout of the RBD (receive buffer descriptor) isn't quite right,
the hardware ended up being implemented differently. Switch to the
correct RBD layout. While at it, remove the now useless extra defines.
Also, switch the CD (completion descriptor) to the right format, which
is basically just a code cleanup because the only field we really used
(rbid) is still in the same place. We may need fragmentation later if
we ever want to use it.

with one mode so we can set to the exact mode used (vht/ht)
and enable larger amsdu sizes for vht.

2.20.1
From: Shahar S Matityahu <[email protected]>
Separate between ini and legacy dump flows to allow adding ini triggers
that are not supported in the legacy flow and to increase readabilty.
iwl_fw_dbg_ini_collect function is now called with legacy trigger id and
_iwl_fw_dbg_ini_collect is called with ini trigger id.
Also make the actual dumping function static so that any dump collection
will go through iwl_fw_dbg_collect_sync.

Ooops, this one should obviously not go through my tree. Johannes, can
you please take it? I've removed from my tree and won't include it as
part of my pull-request.
I'll also check patchwork and make sure it's under Johannes' name.

Cheers,
Luca.

I don't think this makes sense.
If anything, we should pass extack to mac80211_hwsim_new_radio() and do
the entire validation there, but doing the same thing twice in two
places just because of static checkers is useless.
