With the hardware-specific code in place, add all supported device id's,
along with base driver changes to enable 82599 devices.  The devices
being enabled are:

8086:10f7: 82599EB 10 Gigabit KX4 Network Connection
8086:10fb: 82599EB 10 Gigabit Network Connection

The device 8086:10fb is a fully-pluggable SFP+ NIC.

This patch adds the DCB (Data Center Bridging) support for 82599 hardware.
This is similar to how the 82598 DCB code works.

This patch also removes the BCN (Backwards Congestion Notification) netlink
configuration code from the driver.  BCN was a pre-standard congestion
notification framework, and was not what the IEEE body decided upon for
standard congestion management. QCN (802.1Qau), Quantized Congestion
Notification is the accepted standard, which is not supported by 82599,
hence we remove the support altogether.

"cfg80211: add assert_cfg80211_lock() to ensure proper protection"
added assert_cfg80211_lock() calls into various places. At least
one of them, nl80211_send_wiphy(), should not have been there. That
triggers the BUG_ON in assert_cfg80211_lock() and pretty much kills
the kernel whenever someone runs hostapd.. Remove that call and make
assert_cfg80211_lock() use WARN_ON instead of BUG_ON to be a bit more
friendly to users.

It was not a good idea to do a TSF reset on strange IBSS merges to the same BSSID. For example it will break the TSF sync of ath9k completely and it is unnecessary as all hardware I have tested do a TSF sync to a higher value automatically and IBSS merges are only done to higher TSF values. It only need a TSF reset to accept a lower value, when the IBSS network is changed manually.

Do this by indicating the end of the appropriate regions of memory.

Note that MAX_PDA_SIZE should only apply to the PDA block read from
flash/EEPROM, and has been erronously applied to the pdr elements.
Remove the macro, and use the actual PDA size passed down by the caller.

We also fix up some of the types used, marking as much as possible
const, and using void* for the end pointers.

Additional attempts to fix Oops on disconnect, that appear to be successful.
However, some may be extraneous.

The cancel_delayed_work call is probably the most necessary.  The
device_unplugged check may not be necessary.  del_timer_sync may not
be necessary either, but the Oops I was receiving was related to
timers.  Hence the addition.

If we are roaming we allow to follow beacon hints.
Signed-off-by: NLuis R. Rodriguez <lrodriguez@atheros.com>
Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

When devices are world roaming they cannot beacon or do active scan
on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although
we have a good regulatory API some cards may _always_ world roam, this
is also true when a system does not have CRDA present. Devices doing world
roaming can still passive scan, if they find a beacon from an AP on
one of the world roaming frequencies we make the assumption we can do
the same and we also remove the passive scan requirement.

This adds support for providing beacon regulatory hints based on scans.
This works for devices that do either hardware or software scanning.
If a channel has not yet been marked as having had a beacon present
on it we queue the beacon hint processing into the workqueue.

All wireless devices will benefit from beacon regulatory hints from
any wireless device on a system including new devices connected to
the system at a later time.

The current static world regulatory domain is too restrictive,
we can use some 5 GHz channels world wide so long as they do not
touch frequencies which require DFS. The compromise is we must
also enforce passive scanning and disallow usage of a mode of
operation that beacons: (AP | IBSS | Mesh)

We were not protecting last_request there is a small possible race
between an 11d hint and another routine which calls reset_regdomains()
which can prevent a valid country IE from being processed. This is
not critical as it will still be procesed soon after but locking prior
to it is correct.
