* In set_opmode don't handle antenna settings and preserve other STA_ID1 settings
(shouldn't matter because we call it during reset but it makes things cleaner)
Also set properly AP/ADHOC indicator flag on CFG while setting AP/ADHOC modes
and always enable key search mode.

* Properly set BSSID Mask during reset (cache it and reuse it durring set_associd)

* Update beacon_init to flush pending BMISS interrupts and handle setting of adhoc
beacon ATIM policy flag for ad-hoc mode. Also set TSF to 0 to start TSF increment
on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF.

* Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key
function etc so i leave it for now).

Tested on AR5212 (Hainan) and AR5413 and works fine

v2 Set PISR on AR5211+ and ISR on AR5210, got to sleep more ;-)

Remove the SSID from the driver API since now there is no
driver that requires knowing the SSID and I think it's
unlikely that any hardware design that does require the
SSID will play well with mac80211.

This also removes support for setting the SSID in master
mode which will require a patch to hostapd to not try.

We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

Different to readonly reference of netdev->priv, in this driver, netdev->priv
was changed. I use netdev->ml_priv to replace netdev->priv.

The classifier should cover the most common use case and will work
without any special configuration.

The principle of the classifier is to directly access the
task_struct via get_current(). In order for this to work,
classification requests from softirqs must be ignored. This is
not a problem because the vast majority of packets in softirq
context are not assigned to a task anyway. For this to work, a
mechanism is needed to trace softirq context. 

This repost goes back to the method of relying on the number of
nested bh disable calls for the sake of not adding too much
complexity and the option to come up with something more reliable
if actually needed.

I was recently hunting a bug that occurred in network namespace
cleanup.  In looking at the code it became apparrent that we have
and will continue to have cases where if we have anything going
on in a network namespace there will be assumptions that the
loopback device is present.   Things like sending igmp unsubscribe
messages when we bring down network devices invokes the routing
code which assumes that at least the loopback driver is present.

Therefore to avoid magic initcall ordering hackery that is hard
to follow and hard to get right insert a call to register the
loopback device directly from net_dev_init().    This guarantes
that the loopback device is the first device registered and
the last network device to go away.

But do it carefully so we register the loopback device after
we clear dev_boot_phase.
