iwlwifi: fw: don't send GEO_TX_POWER_LIMIT command to FW version 36

2019-10-05T11:14:00+00:00

commit fddbfeece9c7882cc47754c7da460fe427e3e85b upstream.

The intention was to have the GEO_TX_POWER_LIMIT command in FW version
36 as well, but not all 8000 family got this feature enabled.  The
8000 family is the only one using version 36, so skip this version
entirely.  If we try to send this command to the firmwares that do not
support it, we get a BAD_COMMAND response from the firmware.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=204151.

iwlwifi: pcie: handle switching killer Qu B0 NICs to C0

2019-09-06T08:23:50+00:00

[ Upstream commit b9500577d361522a3d9f14da8cf41dc1d824904e ]

We need to use a different firmware for C0 versions of killer Qu NICs.
Add structures for them and handle them in the if block that detects
C0 revisions.

Additionally, instead of having an inclusive check for QnJ devices,
make the selection exclusive, so that switching to QnJ is the
exception, not the default.  This prevents us from having to add all
the non-QnJ cards to an exclusion list.  To do so, only go into the
QnJ block if the device has an RF ID type HR and HW revision QnJ.

iwlwifi: pcie: don't switch FW to qnj when ax201 is detected

2019-09-06T08:23:50+00:00

[ Upstream commit 17e40e6979aaf60f356331bac129df20e1fd74a0 ]

We have a too generic condition that switches from Qu configurations
to QnJ configurations.  We need to exclude some configurations so that
they are not erroneously switched.  Add the ax201 configuration to the
list of exclusions.

iwlwifi: pcie: add support for qu c-step devices

2019-09-06T08:23:50+00:00

[ Upstream commit a7d544d63120061f89459585f06ca44d30842a22 ]

Add support for C-step devices.  Currently we don't have a nice way of
matching the step and choosing the proper configuration, so we need to
switch the config structs one by one.

iwlwifi: mvm: disable TX-AMSDU on older NICs

2019-08-29T06:30:20+00:00

[ Upstream commit cfb21b11b891b08b79be07be57c40a85bb926668 ]

On older NICs, we occasionally see issues with A-MSDU support,
where the commands in the FIFO get confused and then we see an
assert EDC because the next command in the FIFO isn't TX.

We've tried to isolate this issue and understand where it comes
from, but haven't found any errors in building the A-MSDU in
software.

At least for now, disable A-MSDU support on older hardware so
that users can use it again without fearing the assert.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=203315.

iwlwifi: mvm: send LQ command always ASYNC

2019-08-29T06:30:10+00:00

[ Upstream commit cd4d6b0bcd51580efda9ae54ab7b2d630b4147dc ]

The only place where the command was sent as SYNC is during
init and this is not really critical. This change is required
for replacing RS mutex with a spinlock (in the subsequent patch),
since SYNC comamnd requres sleeping and thus the flow cannot
be done when holding a spinlock.
