Net-detect is an option of wowlan to allow the device to
be woken up from suspend mode when configured network is detected.
When user enables net-detect and lets the device enter suspend
state, wowlan firmware will periodically scan until beacon or

Between two scans, wowlan firmware keeps wifi chip in idle mode
to reduce power consumption. If configured networks are detected,

Wake on WLAN(wowlan) is a feature which allows devices
to be woken up from suspend state through wlan events.
When user enables wowlan feature and then let the device
enter suspend state, wowlan firmware will be loaded by
the driver and periodically monitors wifi packets.
Power consumption of wifi chip will be reduced in this
state.
If wowlan firmware detects that specific wlan event
happens, it will issue wakeup signal to trigger resume
process. Driver will load normal firmware and let wifi
chip return to the original state.
Currently supported wlan events include receiving magic packet,
rekey packet and deauth packet, and disconnecting from AP.

Before commit 1e58252e33 ("mwifiex: Fix heap overflow in
mmwifiex_process_tdls_action_frame()"),
mwifiex_process_tdls_action_frame() already had too many magic numbers.
But this commit just added a ton more, in the name of checking for
buffer overflows. That seems like a really bad idea.
Let's make these magic numbers a little less magic, by
(a) factoring out 'pos[1]' as 'ie_len'
(b) using 'sizeof' on the appropriate source or destination fields where
possible, instead of bare numbers
(c) dropping redundant checks, per below.
Regarding redundant checks: the beginning of the loop has this:
if (pos + 2 + pos[1] > end)
break;
but then individual 'case's include stuff like this:
if (pos > end - 3)
return;
if (pos[1] != 1)
return;
Note that the second 'return' (validating the length, pos[1]) combined
with the above condition (ensuring 'pos + 2 + length' doesn't exceed
'end'), makes the first 'return' (whose 'if' can be reworded as 'pos >
end - pos[1] - 2') redundant. Rather than unwind the magic numbers
there, just drop those conditions.

mine and some of Arnds patches that is a good foundation

These are for application to the networking tree so
that can be taken in one separate sweep.
I have tested the patches for a bit using zeroday builds
and some boots on misc IXP4xx devices and haven't run
into any major problems. We might find some new stuff
as a result from the new compiler coverage.
I had to depromote enabling compiler coverage at one
point in the v2 set because it depended on other patches
making the code more generic.
The change in v3 was simply dropping one offending
patch hardcoding base addresses into the driver.
The change in v4 drops a stable@ tag that was
unnecessary.
This v5 is a rebase of the v4 patch set on top of

The IXP4xx driver was initializing the MDIO bus before even
probing, in the callbacks supposed to be used for setting up
the module itself, and with the side effect of trying to
register the MDIO bus as soon as this module was loaded or
compiled into the kernel whether the device was discovered
or not.
This does not work with multiplatform environments.
To get rid of this: set up the MDIO bus from the probe()
callback and remove it in the remove() callback. Rename
the probe() and remove() calls to reflect the most common
conventions.
Since there is a bit of checking for the ethernet feature
to be present in the MDIO registering function, making the
whole module not even be registered if we can't find an
MDIO bus, we need something similar: register the MDIO
bus when the corresponding ethernet is probed, and
return -EPROBE_DEFER on the other interfaces until this
happens. If no MDIO bus is present on any of the
registered interfaces we will eventually bail out.
None of the platforms I've seen has e.g. MDIO on EthB
and only uses EthC, there is always a Ethernet hardware
on the NPE (B, C) that has the MDIO bus, we just might
have to wait for it.

This series includes some misc update relating to reset issue.

of FLR should be separated out from the reset task([patch 3/7 &

pci_error_handlers.reset_prepare() is void type function, so
[patch 6/7] & [patch 7/7] factor some codes related to PF

Currently, the actual work of VF FLR is handled in the reset task,
which is asynchronous. So in some case, if the preparing and
rebuilding are not done, then the VF FLR will trigger some problems,
for example, makes hardware go into chaos.
So this patch separates the process of VF FLR from reset task, and
adds a semaphore to serialize this reset and others.
When FLR's preparing fails, if there has other higher level reset
pending or failing times less than the HCLGE_FLR_RETRY_CNT, this
preparing should be retried, otherwise it will get into a wrong state.
BTW, while the hardware reports misc interrupt during pcie_flr(),
the driver can not receive this interrupt anymore, so disable it
when hclgevf_flr_prepare() return, and re-enable it when enter
hclgevf_flr_done().
Avoid declaring internal function hclgevf_enable_vector(), this patch
also moves its definition forward, and removes unused enum

Add the set of info versions reported by each device driver, including
a description of what the version represents, and what modes (fixed,
running, stored) it reports.

Several drivers document what parameters they support in
a devlink-params-*.txt file. This file is supposed to contain both the
list of generic parameters implemented by the driver, as well as a list
of driver-specific parameters and their descriptions.
It would also be good if the driver documentation included other
driver-specific implementations, such as info versions, devlink
regions, and so forth.
Convert all of these documentation files to reStructuredText, and rename
them to just the driver name. Future changes will include other
driver-specific implementations. Each file will contain a table for the
generic parameters implemented, as well as a separate table for the
driver-specific parameters.
Future sections such as for devlink info versions will be added to these
files. This avoids creating additional devlink-<feature>-<driver> files
for each devlink feature, reducing clutter in the documentation folder.
