The rt2800pci driver uses the same [RT]XWI size
for all chipsets, however some chips requires
different values.
The size of the [RT]XWI structures is a constant
value for a given chipset and it does not depend
on the underlying interface. Add a helper function
which returns the correct values for the actual
chipset and use the new helper both in the rt2800usb
and in the rt2800pci drivers. This ensures that both
drivers are using the correct values.

CSA is only enabled for one interface, but the same limitation applies
for mac80211 too. It checks whether the beacon has been sent (different
approaches for non-EDMA-enabled and EDMA-enabled devices), and completes
the channel switch after that.

The Performance Based Window snooze mechanism is based on uAPSD and is
used in low-medium traffic scenarios, in order to provide better power
performance while insuring low latency and jitter for the incoming traffic.
This patch enables PBW snoozing in case uAPSD is enabled and all ACs are
uAPSD trigger and delivery enabled.

The callers of iwl_drv_start() are probe functions. If a probe
function returns 0, it means it succeeded. So if NULL was returned by
iwl_drv_start(), it would be considered as a success.
Fix this by returning -ENOMEM if the driver struct allocation fails in
iwl_drv_start().

To be able to add more logic to the resume code, refactor it a bit,
moving some status checking/reporting logic into a new function.
The locking becomes a bit odd (one of the new functions now unlocks
the mutex) but this will be required to call new mac80211 APIs in
there later.

In the previous QUERY_PAGES command version we used one command to get the
required amount of boot, init and post init pages. The new version uses the
op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.
In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.
In the pages request event the num_pages field also changed to 32 bits.
In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.
This patch isn't compatible with firmware versions < 5; however, it turns out that the
first GA firmware we will publish will not support previous versions so this should be OK.

Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible
NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev)
condition is met and netdev is NULL. Then, the jump to the 'done' label
calls dev_close() with a netdevice that is NULL. Therefore, only call
dev_close() when we have a netdevice, but one that is not running.
