2d93aee152 iwlwifi: pcie: enable oscillator for L1 exit
Enabling the oscillator consumes slightly more power (100uA)
but allows to make sure that we exit from L1 on time.

Not doing so might lead to a PCIe specification violation
since we might wake up from L1 at the wrong time.
This issue has been identified on 3160 and 7260 only.
On older NICs L1 off is not enabled, on newer NICs (7265),
the issue is fixed.

When the bug occurs the user sees that the NIC has
disappeared from the PCI bridge, any access to the device
returns 0xff.

This fixes:

The iwlwifi conflict was resolved by keeping the code added

change updated all the wireless web site URLs and the other

5ef4acd58a iwlwifi: fix hardware queue programming
Newer devices have 20 (5000 series) or 30 (6000 series)
hardware queues, rather than the 16 that 4965 had. This
was added to the driver a long time ago, but improperly:
the queue registers for the higher queues aren't just
continuations of the registers for the first 16 queues,
they are in other places. Therefore, the hardware would
lock up when trying to activate queue 16 or above and
the device would have to be restarted.

Thanks goes to Emmanuel who identified this and told me
how the queue programming should be done.

Note that we don't use queues 20 and higher today and
doing so needs more work than this.

edc1a3a090 iwlwifi: clean up queue/fifo handling
4965 hardware has 7 queues reserved and the
remaining ones used for aggregation, 5000
and higher need to have 10 reserved. This
is not very clear in the code right now,
unfortunately.

Introduce a new IWL_TX_FIFO_UNUSED constant
and make the queue/FIFO mapping arrays able
to hold that value, and change the setup
code to reserve all queues in the arrays
(the queue number is the index) and use the
new unused constant to not map those queues
to any FIFO.

Additionally, clear up the AC/queue mapping
code to be more understandable. The mapping
is the identity mapping right now, but with
the mapping function I think it's easier to
understand what happens there.

Finally, HCCA isn't implemented at all and
I think newer microcode removed it, so let's
remove all mention of it in the code, some
comments remain for 4965.
