sysfs: add attribute to indicate hw address assignment type

Add addr_assign_type to struct net_device and expose it via sysfs.
This new attribute has the purpose of giving user-space the ability to
distinguish between different assignment types of MAC addresses.

For example user-space can treat NICs with randomly generated MAC
addresses differently than NICs that have permanent (locally assigned)
MAC addresses.
For the former udev could write a persistent net rule by matching the
device path instead of the MAC address.
There's also the case of devices that 'steal' MAC addresses from slave
devices. In which it is also be beneficial for user-space to be aware
of the fact.

This patch also introduces a helper function to assist adoption of
drivers that generate MAC addresses randomly.

qeth: Clear mac_bits field when switching between Layer 2 and Layer 3

This patch fixes a problem that occurs when switching from layer 3 to layer 2
mode. Resetting this mac_bits makes sure that we retrieve our mac address from
the card, otherwise the interface simply would'nt work.

bonding: don't lock when copying/clearing VLAN list on slave

When copying VLAN information to or removing from a slave
during slave addition or removal, the bonding code currently holds
the bond->lock for write to prevent concurrent modification of the
vlan_list / vlgrp.

This is unnecessary, as all of these operations occur under
RTNL.  Holding the bond->lock also caused might_sleep issues for
some drivers' ndo_vlan_* functions.  This patch removes the extra
locking.

bonding: change test for presence of VLANs

After commit ad1afb00393915a51c21b1ae8704562bf036855f
("vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)")
it is now regular practice for a VLAN "add vid" for VLAN 0 to
arrive prior to any VLAN registration or creation of a vlan_group.

This patch updates the bonding code that tests for the presence
of VLANs configured above bonding.  The new logic tests for bond->vlgrp
to determine if a registration has occured, instead of testing that
bonding's internal vlan_list is empty.

The old code would panic when vlan_list was not empty, but
vlgrp was still NULL (because only an "add vid" for VLAN 0 had occured).

Bonding still adds VLAN 0 to its internal list so that 802.1p
frames are handled correctly on transmit when non-VLAN accelerated
slaves are members of the bond.  The test against bond->vlan_list
remains in bond_dev_queue_xmit for this reason.

Modification to the bond->vlgrp now occurs under lock (in
addition to RTNL), because not all inspections of it occur under RTNL.

Additionally, because 8021q will never issue a "kill vid" for
VLAN 0, there is now logic in bond_uninit to release any remaining
entries from vlan_list.

mac80211: proper IBSS locking

IBSS has never had locking, instead relying on some
memory barriers etc. That's hard to get right, and
I think we had it wrong too until the previous patch.
Since this is not performance sensitive, it doesn't
make sense to have the maintenance overhead of that,
so add proper locking.

mac80211: fix IBSS lockdep complaint

Bob reported a lockdep complaint originating in
the mac80211 IBSS code due to the common work
struct patch. The reason is that the IBSS and
station mode code have different locking orders
for the cfg80211 wdev lock and the work struct
(where "locking" implies running/canceling).

Fix this by simply not canceling the work in
the IBSS code, it is not necessary since when
the REQ_RUN bit is cleared, the work will run
without effect if it runs. When the interface
is set down, it is flushed anyway, so there's
no concern about it running after memory has
been invalidated either.

This fixes
https://bugzilla.kernel.org/show_bug.cgi?id=16419

Additionally, looking into this I noticed that
there's a small window while the IBSS is torn
down in which the work may be rescheduled and
the REQ_RUN bit be set again after leave() has
cleared it when a scan finishes at exactly the
same time. Avoid that by setting the ssid_len
to zero before clearing REQ_RUN which signals
to the scan finish code that this interface is
not active.

In practice, this means that regulatory rulesets in a country IE are
often incomplete and might be untrustworthy.  This removes the code

drop_monitor: convert some kfree_skb call sites to consume_skb

Convert a few calls from kfree_skb to consume_skb

Noticed while I was working on dropwatch that I was detecting lots of internal
skb drops in several places.  While some are legitimate, several were not,
freeing skbs that were at the end of their life, rather than being discarded due
to an error.  This patch converts those calls sites from using kfree_skb to

drops.  Tested successfully by myself

mac80211: move QoS-enable to BSS info

Ever since

commit e1b3ec1a2a336c328c336cfa5485a5f0484cc90d
Author: Stanislaw Gruszka <sgruszka@redhat.com>

    mac80211: explicitly disable/enable QoS

mac80211 is telling drivers, in particular
iwlwifi, whether QoS is enabled or not.

However, this is only relevant for station mode,
since only then will any device send nullfunc
frames and need to know whether they should be
QoS frames or not. In other modes, there are
(currently) no frames the device is supposed to
send.

When you now consider virtual interfaces, it
becomes apparent that the current mechanism is
inadequate since it enables/disables QoS on a
global scale, where for nullfunc frames it has
to be on a per-interface scale.

Due to the above considerations, we can change
the way mac80211 advertises the QoS state to
drivers to only ever advertise it as "off" in
station mode, and make it a per-BSS setting.

mac80211: fix aggregation action frame handling with AP VLANs

When aggregation related action frames are enqueued for further work,
and they originate from a STA that is part of an AP VLAN, they are
currently enqueued for the AP interface. This breaks the sta_info_get()
lookup in the actual work function, and because of that, aggregation
sessions are not established for this STA.

Fix this by replacing the sta_info_get call with a call to
sta_info_get_bss.
