When the driver is built into the kernel instead of a module
when the system boots it results in a panic. The order things are built in
results in their initialization order when built into the kernel. Wifi
has to be initialized before mvm or dvm.

The EEPROM reading/parsing code is all mixed in
the driver today, and the EEPROM is parsed only
when we access data from it. This is problematic
because the NVM needs to be parsed and that is
independent of reading it. Also, the NVM format
for new devices will be different and probably
require a new parser.
Therefore refactor the reading and parsing and
create two independent components. Reading the
EEPROM requires direct hardware accesses and
therefore access to the transport, but parsing
is independent and can be done on an NVM blob.

This patch adds the feature to support the test mode operation through
the generic netlink channel NL80211_CMD_TESTMODE between intel
wireless device iwlwifi and the user space application svtool.
The main purpose is to create a transportation layer between the iwlwifi
device and the user space application so that the interaction between the
user space application svtool and the iwlwifi device in the kernel space is
in a way of generic netlink messaging.
The detail specific functions are:
1. The function iwl_testmode_cmd() is added to digest the svtool test command
from the user space application. The svtool test commands are categorized to
three types : commands to be processed by the device ucode, commands to access
the registers, and commands to be processed at the driver level(such as reload
the ucode). iwl_testmode_cmd() dispatches the commands the corresponding handlers
and reply to user space regarding the command execution status. Extra data is
returned to the user space application if there's any.
2. The function iwl_testmode_ucode_rx_pkt() is added to multicast all the spontaneous
messages from the iwlwifi device to the user space. Regardless the message types,
whenever there is a valid spontaneous message received by the iwlwifi ISR,
iwl_testmode_ucode_rx_pkt() is invoked to multicast the message content to user
space. The message content is not attacked and the message parsing is left to
the user space application.
Implementation guidelines:
1. The generic netlink messaging for iwliwif test mode is through NL80211_CMD_TESTMODE
channel, therefore, the codes need to follow the regulations set by cfg80211.ko
to get the actual device instance ieee80211_ops via cfg80211.ko, so that the iwlwifi
device is indicated with ieee80211_ops and can be actually accessed.
Therefore, a callback iwl_testmode_cmd() is added to the structure
iwlagn_hw_ops in iwl-agn.c.
2. It intends to utilize those low level device access APIs from iwlwifi device driver
(ie. iwlagn.ko) rather than creating it's own set of device access functions.
For example, iwl_send_cmd(), iwl_read32(), iwl_write8(), and iwl_write32() are reused.
3. The main functions are maintained in new files instead of spreading all over the
existing iwlwifi driver files.
The new files added are :
drivers/net/wireless/iwlwifi/iwl-sv-open.c
- to handle the user space test mode application command
and reply the respective command status to the user space application.
- to multicast the spontaneous messages from device to user space.
drivers/net/wireless/iwlwifi/iwl-testmode.h
- the commonly referenced definitions for the TLVs used in
the generic netlink messages

This generates a massive reduction in module size:
with debug:

388347 13136 408 401891 621e3 iwlagn.ko (after)
without debug:
text data bss dec hex filename
528575 13072 420 542067 84573 iwlagn.ko (before)
294192 13072 408 307672 4b1d8 iwlagn.ko (after)
This also removes all the IO debug functionality since
it can easily be replaced by tracing, and makes the
code unnecessarily complex.
I haven't done any CPU utilisation measurements, but
given that the hotpaths don't use much IO it is not
likely to have a negative impact; in fact, the size
reduction will reduce cache pressure which possibly
improves performance.
Finally, an unused function or two were removed.

In order to simplify the flow, and make new

processing for modern AGN (5000 and newer)
from RXON processing for the older 3945 and
4965 devices. Avoid changing these old ones
to avoid regressions and move their code to
a new file (iwl-legacy.c). 4965 gets the
commit_rxon that used to be common for all
AGN devices, but with removed PAN support.
The new RXON processing is more central and
does more work in committing, so that it is
easier to follow.
To make it more evident what is split out
for legacy, split the necessary operations
for that into a new struct iwl_legacy_ops.
Those parts that still exist in the new AGN
code don't need to be parametrized.
