Don Fry 6516174d1a iwlwifi: Move ucode pointers to iwl_fw
The ucode image is a ucode related thing not a transport one.  Move them.

Johannes Berg 1ee158d838 iwlwifi: move workqueue to priv
In order to separate the different parts of the
driver better, we are reducing the shared data.
This moves the workqueue to "priv", and removes
it from the transport. To do this, simply use
schedule_work() in the transport.

Don Fry edf3833406 iwlwifi: move all ucode routines to iwl-ucode.c
The routines dealing with the ucode are spread through several files.
Move them all to the same file and create a iwl-ucode.h file with the
ucode file definitions.

Emmanuel Grumbach 1df06bdc6f iwlwifi: stop_hw replace enable_rfkill_int
This trans_ops->stop_hw leaves the RFKILL interrupt enabled,
we can call that one instead of enable_rfkill_int. By that,
we reduce the numbers of acceesses to the NIC from the upper
layers.

Johannes Berg 7428994d79 iwlagn: finer-grained HT disable
At least while debugging, a lot of people use
11n_disable=1 to disable HT completely. To be
able to figure out what parts of HT cause the
problems we see, make the parameter a bitmap,
allowing to disable all of HT and aggregation
(TX/RX) separately.

Johannes Berg a7e12c8e22 iwlagn: fix HW crypto for TX-only keys
Group keys in IBSS or AP mode are not programmed
into the device since we give the key to it with
every TX packet. However, we do need mac80211 to
create the MMIC & PN in all cases. Move the code
around to set the key flags all the time. We set
them even when the key is removed again but that
is obviously harmless.

Johannes Berg a69cd040d0 iwlagn: explicitly program P2P QoS parameters
In P2P device mode, the device needs to have valid
QoS parameters. We currently have those because we
program parameters from any virtual interface into
all contexts, but not only do we want to get rid of
this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.

Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.

This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.
