Variable section_table.size is a u32 and so cannot be less than
zero, hence the less than zero check is redundant and can be
removed.

Some platform(BIOS) blocks legacy interrupts (INTx), and only allows MSI
for WLAN device. So adding a quirk to list those machines and set
use_msi automatically.
Adding the following platforms to the quirk.
Dell Inspiron 24-3460
Dell Inspiron 3472
Dell Inspiron 14-3473
Dell Vostro 3262

On new Intel platforms like ApolloLake, legacy interrupt mechanism
(INTx) is not supported, so WLAN modules are not working because
interrupts are missing, therefore this patch is to add MSI support to
ath9k. With module paremeter "use_msi=1", ath9k driver would try to
use MSI instead of INTx.

====================
wireless-drivers-next patches for 4.16
Here are patches which have been accumulating over the holidays and
after the New Year. Business as usual and nothing special really
standing out.
But what's noteworthy here is that Larry Finger is stepping down as
the rtlwifi maintainer. He has been maintaining rtlwifi since it was
applied back in 2010 in commit 0c8173385e54 ("rtl8192ce: Add new
driver") and it has been no easy role trying to juggle between the
vendor, demanding upstream community and users. So big thank you to
Larry for all his efforts!

BPF alignment tests got a conflict because the registers
are output as Rn_w instead of just Rn in net-next, and
in net a fixup for a testcase prohibits logical operations
on pointers before using them.
Also, we should attempt to patch BPF call args if JIT always on is
enabled. Instead, if we fail to JIT the subprogs we should pass
an error back up and fail immediately.

in case there is a FW assert during the suspend procedure

Since driver does not report hardware dynamic power saving cap,
this is up to the mac80211 to manage power saving timeout and
state machine, using the ieee80211 config callback to report
PS changes. This patch enables/disables PS mode according to
the new configuration.
Remove old behaviour enabling PS mode in a static way, this make
the device unusable when power save is enabled since device is
forced to PS regardless RX/TX traffic.

Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.
Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:
modprobe ath10k_core coredump_mask=0xffffffff
When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

For memory dump support (it consumes quite a lot of memory) we need to control
what is exactly stored to the crash dump. Add a module parameter call
coredump_mask to do that. It's a bit mask of these values:
enum ath10k_fw_crash_dump_type {
ATH10K_FW_CRASH_DUMP_REGISTERS = 0,
ATH10K_FW_CRASH_DUMP_CE_DATA = 1,
ATH10K_FW_CRASH_DUMP_MAX,
};
For example, if we only want to store CE_DATA we would enable bit 2:
modprobe ath10k_core coredump_mask=0x2

Current hw_scan implementation does not trigger offloaded
hardware scan and seems to only put the device in a kind of
listening mode (beacon/probe-response) for software scan.
Since no probe request are generated by the software, current
scanning method is similar to a passive scan.
This patch introduces support for 'true' hardware offloaded scan.
Hardware scan is configured and started via the start-scan-offload
firmware message. Once scan has been completed a scan indicator
message is received from firmware.
Moreover, this patch includes support for directed probe-request,
allowing connection with hidden APs. It also fixes scan issues with
band-steering AP which are not 'visible' with passive scan (due to
hidden ssid in beacons).
Let's keep the 'legacy' scanning method in case scan-offload is not
supported.
