Subject: iwlwifi: pcie: implement GRO without NAPI
Use the new NAPI infrastructure added to mac80211 to get
GRO. We don't really implement NAPI since we don't have
a real poll function and we never schedule a NAPI poll.
Instead of this, we collect all the packets we got from a
single interrupt and then call napi_gro_flush().
This allows us to benefit from GRO. In half duplex medium
like WiFi, its main advantage is that it reduces the number
of TCP Acks, hence improving the TCP Rx performance.
Since we call the Rx path with a spinlock held, remove
the might_sleep mention from the op_mode's API.

Subject: iwlwifi: mvm: dump Rx FIFO when the firmware asserts
The Rx FIFO includes valuable data - dump it when the FW
asserts. Also - free the SRAM and Rx FIFO when we create
the file, and don't collect new SRAM / Rx FIFO if the
previous file hasn't been collected through debugfs yet.
Also - add a comment to saying that the ASSERT output should
not be modified since we have automatic scripts that monitor
this output.

From d15a747fc8462b3f7a40ba5c16678a38f71e12c8 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Thu, 27 Mar 2014 18:53:12 +0200
Subject: iwlwifi: mvm: don't use d3 fw if d0i3 is used
bail out from the suspend/resume callbacks if
d0i3 is used.
declare support for ANY wowlan trigger (i.e.
normal operation).
On resume, we shouldn't execute the d0i3 exit
flow (which might disconnect stations, etc.)
until mac80211 was resumed.
Add new flags to indicate we are in suspend,
and call the pending exit work on resume.
Since the resume flow can take some time, add
a new EXIT_WORK reference type to prevent going
back to d0i3 at this stage.

Subject: iwlwifi: mvm: prevent nic to powered up at driver load
A few devices aren't allowed to be powered up at driver
load time. Add "power_up_nic_in_init" flag to iwl_cfg
structure to customize the load flow according to the
device.

From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>
Date: Tue, 22 Oct 2013 05:01:12 +0200
Subject: iwlwifi:mvm: Add AP/GO channel switch support
Publish WIPHY_FLAG_HAS_CHANNEL_SWITCH if the fw supports
newly introduced IWL_UCODE_TLV_API_CSA_FLOW.
When CSA starts, save the switching vif inside mvm and during the CSA period
configure fw with a new beacon after each beacon transmission in order to
update the csa counters.
Also, handle correctly the CSA unbind-bind flow which is triggered by mac80211
when the actual channel switch happens.

The 8000 family products need a file on the file system
which is used as NVM. This file is a must, if no filename
is supplied as module parameter, use a default filename.

Subject: iwlwifi: remove CMD_SYNC
CMD_SYNC is really 0 which is confusing:
if (cmd.flags & CMD_SYNC) is always false.
Fix this by simply removing its definition.
