iwlwifi: mvm: support version 7 of the SCAN_REQ_UMAC FW command

2017-11-30T08:40:59+00:00

commit dac4df1c5f2c34903f61b1bc4fc722e31b4199e7 upstream.

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not
backwards compatible.  The driver needs to detect and use the new API
format when the firmware reports it, otherwise the scan command will
not work properly, causing a command timeout.

Fix this by adding a TLV that tells the driver that the new API is in
use and use the correct structures for it.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=197591

iwlwifi: fix PCI IDs and configuration mapping for 9000 series

2017-11-30T08:40:59+00:00

commit dbc89253a7e15f8f031fb1eeb956de91204655e3 upstream.

A lot of PCI IDs were missing and there were some problems with the
configuration and firmware selection for devices on the 9000 series.
Fix the firmware selection by adding files for the B-steps; add
configuration for some integrated devices; and add a bunch of PCI IDs
(mostly for integrated devices) that were missing from the driver's
list.

Without this patch, a lot of devices will not be recognized or will
try to load the wrong firmware file.

iwlwifi: pcie: sort IDs for the 9000 series for easier comparisons

commit 1105a337375258515ed09b92a83fd7bfd6775958 upstream.

It's hard to find values that are missing in the list, so sorting the
values and comparing them makes it much easier.  To simplify this
task, sort the devices in the list.

p54: don't unregister leds when they are not initialized

2017-11-30T08:40:52+00:00

commit fc09785de0a364427a5df63d703bae9a306ed116 upstream.

ieee80211_register_hw() in p54_register_common() may fail and leds won't
get initialized. Currently p54_unregister_common() doesn't check that and
always calls p54_unregister_leds(). The fix is to check priv->registered
flag before calling p54_unregister_leds().

iwlwifi: fix firmware names for 9000 and A000 series hw

2017-11-30T08:40:46+00:00

commit c2c48ddfc8b03b9ecb51d2832b586497b37531bc upstream.

iwlwifi 9000 and a0000 series hw contains an extra dash in firmware
file name as seeen in modinfo output for kernel 4.14:

firmware:       iwlwifi-9260-th-b0-jf-b0--34.ucode
firmware:       iwlwifi-9260-th-a0-jf-a0--34.ucode

firmware:       iwlwifi-QuQnj-a0-jf-b0--34.ucode

firmware:       iwlwifi-Qu-a0-jf-b0--34.ucode
firmware:       iwlwifi-Qu-a0-hr-a0--34.ucode

Fix that by dropping the extra adding of '"-"'.
