iwlagn: rewrite HW crypto
As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).
To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.
Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.
Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.
Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

iwlwifi: support the svtool messages interactions through nl80211 test mode
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
