* 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.

Since adm8211 currently doesn't implement IBSS mode anyway,

The SSID programmed into the device is used by the ucode only

because it doesn't fit with the mac80211/hostapd programming

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.

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.

The atmel_serial driver is mismanaging its clock by leaving it on at all
times ...  the whole point of clock management is to leave it off unless
it's actively needed, which conserves power!!

Although the kernel doesn't actually hang without my fix, it does
discard quite a lot of early console output.

The result still looks correct:

          usart        users= 1 on   35000000 Hz, for atmel_usart.0
          usart        users= 0 off  35000000 Hz, for atmel_usart.2

commit 3e680aae ("fb: convert
lock/unlock_kernel() into local fb mutex") introduced several deadlocks
in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion,
unlike lock_kernel().  This broke frame buffer applications on 64-bit
systems with a 32-bit userland.

commit 120a3747 ("framebuffer compat_ioctl
deadlock") fixed one of the deadlocks.

This patch fixes the remaining deadlocks:
  - Revert commit 120a3747,
  - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(),
  - Change all callsites of fb_ioctl() where info->lock is already held to
    call do_fb_ioctl() instead,
  - Add sparse annotations to all routines that take info->lock.

  vc_data in include/linux/console_struct.h .
  In drivers/char/vt.c only 5 of these 8 unsigned ints get initialized

Problem 2 (open):
  Upcoming displays will have more than 256 columns of text leading to

As a consequence, jumbo frames would not be discarded as intended.
