Emmanuel Grumbach 247c61d625 iwlagn: remove the callback in host commands
Before this patch, the upper layer could register a callback for each
host command. This mechanism allowed the upper layer to have
different callbacks for the same command ID. In fact, it wasn't used
and the rx_handlers is enough: same callback for all the command with
a specific command ID.

The iwl_send_add_station needs the access the command that was sent
while handling the response (regardless if the command was sent in
SYNC or ASYNC mode). So now, all the handlers receive the host
command that was sent. This implies a change in the handler signature.

The reclaim flow is really transport related. Define a simple API to allow the
upper layer to request from the transport layer to reclaim packets until an
index written in the Tx response / BA notification.
The transport layer prepares a list of the packets that are being freed and
passes this list to the upper layer.
Between the two layers, the CB of the skb is used to pass a pointer to the
context (BSS / PAN) in which the skb was sent.

Emmanuel Grumbach e6bb4c9c00 iwlagn: bus layer chooses its transport layer
Remove iwl_transport_register which was a W/A. The bus layer knows what
transport to use. So now, the bus layer gives the upper layer a pointer to the
iwl_trans_ops struct that it wants to use. The upper layer then, allocates the
desired transport layer using iwl_trans_ops->alloc function.

As a result of this, priv->trans, no longer exists, priv holds a pointer to
iwl_shared, which holds a pointer to iwl_trans. This required to change all the
calls to the transport layer from upper layer. While we were at it, trans_X
inlines have been renamed to iwl_trans_X to avoid confusions, which of course
required to rename the functions inside the transport layer because of
conflicts in names. So the static API functions inside the transport layer
implementation have been renamed to iwl_trans_pcie_X.

Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is
confusing since the registration doesn't mean to request IRQ, so I added a
handler for that.

Meenakshi Venkataraman 207ecc5eab iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic state
WiFi throughput drops drastically when BT is turned on, BT and WiFi
are simultaneously transmitting/receiving traffic. This is particularly true
when BT has higher priority over WiFi, and hence the device defers TX frames.
The AP assumes that the channel is bad and reduces the data rate, implying
longer airtime, which exacerbates the problem further, resulting ultimately
in what is popularly called the "death-spiral" phenomenon. The use of PS-poll
in such scenarios guarantees a low but consistent throughput.

Since the death-spiral phenomenon is observed only when the RSSI is low, use
PS-poll only when RSSI is low and disable when high, with a known hysterisis.

This feature specifies the high and low thresholds and implements the
callbacks registered with mac80211, which will be called when threshold events
occur.

Bus specific layer must know how to return the struct device* of the device.
Implement that as a callback of iwl_bus_ops and use that callback instead of

Since the struct device * is needed in hot path, iwl_bus holds a pointer to it

Johannes Berg 4ce7cc2b09 iwlagn: support multiple TBs per command
The current "huge" command handling is a bit
confusing, and very limited since only one
command may be huge at a time. Additionally,
we often copy data around quite pointlessly
since we could instead map the existing scan
buffer for example and use it directly.

This patch makes that possible. The first
change is that multiple buffers may be given
to each command (this change was prepared
earlier so callsites don't need to change).
Each of those can be mapped attached to a TB
in the TFD, and the command header can use a
TB (the first one) in the TFD as well.

Doing this allows getting rid of huge commands
in favour of mapping existing buffers. The
beacon transmission is also optimised to not
copy the SKB at all but use multiple TBs.

If a device error happens while the uCode is

to restart the device (which will likely fail
again, but that's not the issue here). During
this new restart, we turn off the device, but
as the uCode failed to initialise it already
is turned off. As a consequence, grabbing NIC
access will fail and cause excessive messages
and hangs.

To fix this issue, introduce a new status bit

it isn't already disabled.

Johannes Berg 0da0e5bf15 iwlagn: clean up & autodetect statistics
There's no need to keep both normal and BT statistics
versions around all the time in memory when we only
use a subset of both. So keep only the subsets that
we need in memory, depending on the debug config).

Also, in doing so, we can remove all the calls to
iwl_bt_statistics() in the driver as we'll just
access the copied statistics now.

Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).

Warn upon encountering a statistics command from the
ucode that isn't known, so we will find such issues
earlier in the future.

Garen Tamrazian 68b993118f iwlagn: fix radar frame rejection
The microcode may sometimes reject TX frames when
on a radar channel even after we associated as it
clears information during association and needs to
receive a new beacon before allowing that channel
again. This manifests itself as a TX status value
of TX_STATUS_FAIL_PASSIVE_NO_RX. So in this case,
stop the corresponding queue and give the frame
back to mac80211 for retransmission. We start the
queue again when a beacon from the AP is received
which will make the regulatory enforcement in the
device allow transmitting again.

Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.

This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.

The following drivers have been updated to reflect the API changes:
iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
