Add new commands to the hwsim generic netlink family to allow
creating and destroying radios on the fly. The number of channels
a radio supports can be specified when it's created, if it isn't
the module parameter will be used as default.
This should be extended in the future to allow other parameters
to be specified, e.g.
* list of channels
* interface combinations, particularly P2P_DEVICE support
* regtest
* and pretty much all other hardware capabilities

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:
- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
instead of lower device which misses the necessary txq synchronization for
lower device such as txq stopping or frozen required by dev watchdog or
control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
when tso is disabled for lower device.
Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.
With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.
In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

If a uAPSD service period ends with an MMPDU, we currently just
send that MMPDU, but it obviously won't get the EOSP bit set as
it doesn't have a QoS header. This contradicts the standard, so

When a response for PS-Poll or a uAPSD trigger frame is sent, the
more-data bit should be set according to 802.11-2012 11.2.1.5 h),
meaning that it should indicate more data on the relevant ACs
(delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.)
In, for example, the following scenario:
* 1 frame on VO queue (either in driver or in mac80211)
* at least 1 frame on VI queue (in the driver)
* both VO/VI are delivery-enabled
* uAPSD trigger frame received
The more-data flag to the driver would not be set, even though
it should be.
While fixing this, I noticed that we should really release frames
from multiple ACs where there's data buffered in the driver for
the corresponding TIDs.
To address all this, restructure the code a bit to consider all
ACs if we only release driver frames or only buffered frames.
This also addresses the more-data bug described above as now the
TIDs will all be marked as released, so the driver will have to
check the number of frames.
While at it, clarify some code and comments and remove the found
variable, replacing it with the appropriate sw/hw release check.

So instead of using drm_modeset_lock_all() just grab the

The recent patch to improve guest receive side flow control (ca2f09f2) had a
slight flaw in the wait condition for the vif thread in that any remaining
skbs in the guest receive side netback internal queue would prevent the
thread from sleeping. An unresponsive frontend can lead to a permanently
non-empty internal queue and thus the thread will spin. In this case the
thread should really sleep until the frontend becomes responsive again.
This patch adds an extra flag to the vif which is set if the shared ring
is full and cleared when skbs are drained into the shared ring. Thus,
if the thread runs, finds the shared ring full and can make no progress the
flag remains set. If the flag remains set then the thread will sleep,
regardless of a non-empty queue, until the next event from the frontend.

====================
nf_tables updates for net-next
The following patchset contains the following nf_tables updates,
mostly updates from Patrick McHardy, they are:
* Add the "inet" table and filter chain type for this new netfilter
family: NFPROTO_INET. This special table/chain allows IPv4 and IPv6
rules, this should help to simplify the burden in the administration
of dual stack firewalls. This also includes several patches to prepare
the infrastructure for this new table and a new meta extension to
match the layer 3 and 4 protocol numbers, from Patrick McHardy.
* Load both IPv4 and IPv6 conntrack modules in nft_ct if the rule is used
in NFPROTO_INET, as we don't certainly know which one would be used,
also from Patrick McHardy.
* Do not allow to delete a table that contains sets, otherwise these
sets become orphan, from Patrick McHardy.
* Hold a reference to the corresponding nf_tables family module when
creating a table of that family type, to avoid the module deletion
when in use, from Patrick McHardy.
* Update chain counters before setting the chain policy to ensure that
we don't leave the chain in inconsistent state in case of errors (aka.
restore chain atomicity). This also fixes a possible leak if it fails
to allocate the chain counters if no counters are passed to be restored,
from Patrick McHardy.
* Don't check for overflows in the table counter if we are just renaming
a chain, from Patrick McHardy.
* Replay the netlink request after dropping the nfnl lock to load the
module that supports provides a chain type, from Patrick.
* Fix chain type module references, from Patrick.
* Several cleanups, function renames, constification and code
refactorizations also from Patrick McHardy.
* Add support to set the connmark, this can be used to set it based on
the meta mark (similar feature to -j CONNMARK --restore), from
Kristian Evensen.
* A couple of fixes to the recently added meta/set support and nft_reject,
and fix missing chain type unregistration if we fail to register our
the family table/filter chain type, from myself.

Close avn_cstates array with correct marker to avoid overflow
in function intel_idle_cpu_init().
[rjw: The problem was introduced when commit 22e580d07f was merged
on top of eba682a5ae (intel_idle: shrink states tables).]
Fixes: 22e580d07f (intel_idle: Fixed C6 state on Avoton/Rangeley processors)
