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

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.

AFAICT, none of these amount to real bugs. But this reduces warning
spam from sparse w/o significantly affecting readability of the code (IMHO).

rtl8180: improve signal reporting for rtl8185 hardware
The existing code seemed to be somewhat based on the datasheet, but
varied substantially from the vendor-provided driver. This mirrors the

specifics for the rtl8180 hardware. Those details are a bit muddled...

Noticed while I was working on dropwatch that I was detecting lots of internal

freeing skbs that were at the end of their life, rather than being discarded due

mac80211: set carrier on for monitor interfaces on ieee80211_open
If a station interface is reused as monitor interface it is possible that
the carrier is still set to off. This breaks packet injection on that
monitor interface.

for other interface types (e.g. adhoc, mesh point, ap).

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.
