Subject: iwlwifi: add support of FPGA fw

Load FW according to NIC type,
taking into account simulation, if exists.
This is determined by a prph register.

Subject: iwlwifi: distinguish different RF modules in A000 devices

Newer versions of A000 devices come with two diffenent RF modules.
The PCI_ID, the subsystem ID and the RF ID are identical in these two cases,
so we need to differentiate them by using the CSR_HW_RF_ID register-
in order to load the appropriate firmware.

Subject: iwlwifi: nvm: set the correct offsets to 3168 series

The driver currently handles two NVM formats,
one for 7000 family and below, and one for 8000 family and above.
The 3168 series uses something in between,
so currently the driver uses incorrect offsets for it.
Fix the incorrect offsets.

From dd05f9aab4426ff178b12d601e50d19d336eba30 Mon Sep 17 00:00:00 2001
From: Shahar S Matityahu <shahar.s.matityahu@intel.com>
Date: Sun, 30 Jul 2017 17:33:48 +0300
Subject: iwlwifi: pcie: dynamic Tx command queue size

Devices in the A000 family can use a different size for the command queue.
To allow this, make the command queue size configurable and set the size
for A000 devices to 32.

Subject: iwlwifi: define minimum valid address for umac_error_event_table in
 cfg

We now have two different minimum valid values for
umac_error_event_table.  To avoid hardcoding the minimum value in the
driver, add a value to cfg where it can be read from.

Subject: iwlwifi: fix firmware names for 9000 and A000 series hw

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-hr-a0--34.ucode
firmware:       iwlwifi-QuQnj-a0-jf-b0--34.ucode
firmware:       iwlwifi-QuQnj-f0-hr-a0--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 '"-"'.
