For 6x00 and 6x50 series devices, APIv4 is the lowest firmware version
driver can support. This is also the lowest API version available to the
public so there is no need for backward compatibility support for the
earlier API versions.

In the paged rx patch (4854fde2), I introduced a bug that could possibly
touch an already freed page. It is fixed by avoiding the access in this
patch. I've also added some comments so that other people touching the
code won't make the same mistake. In the future, if we cannot avoid
access the page after being handled to the upper layer, we can use
get_page/put_page to handle it. For now, it's just not necessary.

It also fixed a debug message print bug reported by Stanislaw Gruszka

Consolidate most iwlXXXX_apm_init() functions into single iwl_apm_init().
Keep iwl3945_apm_init(), but leverage iwl_apm_init() for most functionality.
Update 4965 init sequence to follow most recent factory recommendations.

Add following members to struct iwl_cfg to guide the init sequence:
pll_cfg_val (replaces needs_pll_cfg), set_l0s, use_bsm

Move L0S enable/disable from nic_config() functions to iwl_apm_init().
This satisifies the "FIXME: put here L1A -L0S w/a" notice, and complies
with factory-recommended sequence.

But there was no code that anywhere that was able to set this
variable to true. So all 11d code was dead for almost a year and no one

First, we reduce the number of hardware retries to 0 (ie 2 real retries
for each rate). Next, when we report the retries to mac80211, we always
report a retry count of 1 (it seems to be 2 in fact, but using 2 seems
to lead to wrong performance for some reason). We use a state machine to
determine the real fate of a packet based on the 802.11 ACK and what the
Zydas hardware is saying when a real retry occurs. The real retry rates
are encoded in a static array. It has been tested with both zd1211 and
zd1211b hardware. Of course, since the Zydas hardware is not reporting
retries accurately, we are just doing our best in order to get the best
performance (ie higher throughput).

For static power save, the actual intervals are calculated by driver based on
the default table and DTIM flag, then sent to uCode when the scheme
is changed.

Three tables are defined based on DTIM period.
	1. DTIM 0 - 2
	2. DTIM 3 - 10
	3. DTIM > 11

The actual number of DTIM a station may miss may not exceed the
following:
	. Only 1 DTIM may be skipped at PI=4 when allowed
	. Only 2 DTIMs may be skipped at PI=5 when allowed
	. DTIM may be skipped only 5 sec after last activity
	. DTIM may be skipped only 30 sec after connection establishment

Only allow user to override the power_level when rf is ready to make sure
power level gets changed upon request.
