Currently there is one to one function between device id to it's ucode.
The new generation devices allows to combine different phy and mac images.
Now we have two different ucode images with the same device id.
Read RF ID to identify phy image and overwrite it if needed.

If a host command was queued while in runtime suspend, it would go out
before the D0I3_END_CMD was sent. Sometimes it works, but sometimes
it fails, and it is obviously the wrong thing to do.
To fix this, have the opmode take a reference before sending a SYNC
command and make the pcie trans wait for the runtime state to become
active before actually queueing the command.

There is a debugfs knob to configure the maximal length
of the A-MSDU. If this value is not 0 (which is the
default), allow Tx A-MSDU even if the rate control
disallows it.
While at it, add "unlikely" to the if that limits the
length of the A-MSDU based on the debugfs hook.

It's cleaner to always call the iwl_trans_ref/unref() functions

Add a timer in order to release expired frames from the
reorder buffer.
This is needed since some APs do not retransmit frames
to fill in the reorder holes and in TCP it results with
a complete stall of traffic.
This has a few side effects on the general design:
The nssn may not reflect the the head of the reorder buffer.
This situation is valid, and packets with SN lower than the
reorder buffer head will be dropped.
Another side effect is that since the reorder timer might expire
we need to lock the reorder buffer.
This however is fine since the locking is only inside a
single reorder buffer between RX path and reorder timeout and
there is no outside contention.

Next hardware will direct packets to core based on the TCP/UDP
streams.
This logic can create holes in reorder buffer since packets that
belong to other stream were directed to a different core.
However, those are valid holes and the packets can be indicated
in L3 order.
The hardware will utilize a mechanism of informing the driver of
the normalized ssn and the driver shall release all packets that
SN is lower than the nssn.
This enables managing the reorder across the queues without sharing
any data between them.
The reorder buffer is allocated and released directly in the RX path
in order to avoid various races between control path and rx path.
The code utilizes the internal messaging to notify rx queues of when
to delete the reorder buffer.

According to the spec when a BA session is started there
is a timeout set for the session in the ADDBA request.
If there is not activity on the TA/TID then the session
expires and a DELBA is sent.
In order to check for the timeout, data must be shared
among the rx queues.
Add a timer that runs as long as BA session is active
for the station and stops aggregation session if needed.
This patch also lays the infrastructure for the reordering
buffer which will be enabled in the next patches.

Currently the sync notification is a type of notification. However, it
is better fitted as an attribute of a notification, since there might

mac80211 will call the driver whenever there is a race between
RSS queues and control path that requires a processing of all
pending frames in RSS queues.
Implement that by utilizing the internal notification mechanism:
queue a message to all queues. When the message is received on
a queue it decrements the atomic counter. This guarantees that
all pending frames in the RX queue were processed since the message
is in order inside the queue.

* fix P2P rates (and possibly other issues)
Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

The TSO code creates A-MSDUs from a single large send. Each
A-MSDU is an skb and skb->len doesn't include the number of
bytes which need to be added for the headers being added
(subframe header, TCP header, IP header, SNAP, padding).
To be able to set the right value in the Tx command, we
put the number of bytes added by those headers in
driver_data in iwl_mvm_tx_tso and use this value in
iwl_mvm_set_tx_cmd.
The problem by setting this value in driver_data is that
it overrides the ieee80211_tx_info. The bug manifested
itself when we send P2P related frames in CCK since the
rate in ieee80211_tx_info is zero-ed. This of course is
a violation of the P2P specification.
To fix this, copy the original ieee80211_tx_info to the
stack and pass it to the functions which need it.
Assign the number of bytes added by the headers to the
driver_data inside the skb itself.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

The firwmare file can come with data that is relevant for paging. This
data is availablet to the firmware upon request, but it stored in the
host's memory. During the firmware init flow, the driver configures the
firmware so that the firwmare knows where is the data.
When paging is used, the variable paging_mem_size is the number of bytes
that are available through paging. This variable is not zeror-ed if the
driver fails to configure the paging in the firmware, but the memory is
freed which is inconsistent.
This inconsistency led to a NULL pointer dereference in the code that
collects the debug data.
Fix this by zero-ing the paging_mem_size variable and NULLify the
relevant pointers, so that the code that collects the debug data will
know that the paging data is not available.

The firwmare name for 8000 is iwlwifi-8000C. The C is
appended based on a value read from a register. This
allows to load different firwmare versions based on
the hardware step during development. Now that the
hardware development is completed, we can hard code
the 'C' and along the way, fix the input to
MODULE_FIRMWARE.

This patch processes sub AMSDU frame received in AP mode.
If a packet is multicast/broadcast, it is sent to kernel/upper
layer as well as queued back to AP TX queue so that it can be
sent to other associated stations.
If a packet is unicast and RA is present in associated station list,
it is again requeued into AP TX queue.
If a packet is unicast and RA is not in associated station list,
packet is forwarded to kernel to handle routing logic.

In some of the non-success return paths, the memory allocated by
iwl4965_sta_alloc_lq() in iwl4965_alloc_bcast_station() is not freed.
In particular:
- if the card isn't ready after il4965_prepare_card_hw()
- if the card is hardware-rfkilled
In the hardware rfkilled path, the driver enables the rfkill
interrupt. When the card is unrfkilled and this interrupt is raised
we end up calling il4965_bg_restart() which calls __il4965_up() which
calls iwl4965_alloc_bcast_station() again.
