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.

iwlwifi driver supports multiple devices. Since some device needs
special configuration we create a new iwl_nic_ops structure which is
configurable per device. Currently there is only one function pointer
inside this structure: additional_nic_config().
The iwl_nic_ops structure is added to the top level in struct iwl_ops,
making it easier to change per device. Duplication of the iwl_lib_ops
structure is no longer needed.
With this new ops the previous function pointer set_calib_version is
no longer needed since it is just a per device nic configuration.
As part of the code restructuring, a bug is addressed. Indication of
calib version to uCode is only needed for 6050 devices, however,

which DC calib is needed. To fix this, create iwl6050_ops for 6050

Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.
In order to fix all of this, we need to take a step
back and see what we need to achieve:
* we need RTS/CTS protection if requested by
the AP for the BSS, mac80211 tells us this
* in that case, CTS-to-self should only be
enabled when mac80211 tells us
* additionally, as a hardware workaround, on
some devices we have to protect aggregated
frames with RTS
To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.
To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).
Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.
Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

Adding flush callback support in the driver. Two type of flush can be
issued by mac80211:
1. drop = true: frame drop is ok, issue REPLY_TXFIFO_FLUSH host command
to uCode to drop all the frames in tx fifo queues; then return the
control back to mac80211
2. drop = false: wait for either all the frames in tx fifo queues been
transmitted, or timeout; then return the control back to mac80211
If the flush request coming from mac80211, mac80211 will make sure there
are no additional frames push down to driver before flush operation is
completed.

Radio calibration (chain noise and sensitivity) should be allowed to
be disabled from debugfs if compiled with CONFIG_IWLWIFI_DEBUGFS. For both
6000g2a and 6000g2b, the parameters are missing in "cfg", which cause
user can not disable the radio calibration manually; add the support to
allow the operation.

The rate table in the bcast LQ is computed only when the station is
allocated, and chooses the lowest rate for the band. Because of when this
occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz
beaconing mode, this rate will prevent beacons from being sent and any other
packets from being received.
We can fix this by re-initializing the bcast station's LQ command when the
channel is changed.

Different devices have different calibration requirement,
some need DC calibration and some don't; make it a cfg parameter
for easy management.
