Currently the AF-specific hook functions override the chain-type specific
hook functions. That doesn't make too much sense since the chain types
are a special case of the AF-specific hooks.
Make the AF-specific hook functions the default and make the optional
chain type hooks override them.
As a side effect, the necessary code restructuring reduces the code size,

br_multicast_set_hash_max() is called from process context in
net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function.
br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock),
which can deadlock the CPU if a softirq that also tries to take the
same lock interrupts br_multicast_set_hash_max() while the lock is
held . This can happen quite easily when any of the bridge multicast
timers expire, which try to take the same lock.
The fix here is to use spin_lock_bh(), preventing other softirqs from
executing on this CPU.
Steps to reproduce:
1. Create a bridge with several interfaces (I used 4).
2. Set the "multicast query interval" to a low number, like 2.
3. Enable the bridge as a multicast querier.
4. Repeatedly set the bridge hash_max parameter via sysfs.

Sathya Perla posted a patch trying to address following problem :
<quote>
The vxlan driver sets itself as the socket owner for all the TX flows
it encapsulates (using vxlan_set_owner()) and assigns it's own skb
destructor. This causes all tunneled traffic to land up on only one TXQ
as all encapsulated skbs refer to the vxlan socket and not the original
socket. Also, the vxlan skb destructor breaks some functionality for
tunneled traffic like wmem accounting and as TCP small queues and
FQ/pacing packet scheduler.
</quote>
I reworked Sathya patch and added some explanations.
vxlan_xmit() can avoid one skb_clone()/dev_kfree_skb() pair
and gain better drop monitor accuracy, by calling kfree_skb() when
appropriate.
The UDP socket used by vxlan to perform encapsulation of xmit packets
do not need to be alive while packets leave vxlan code. Its better
to keep original socket ownership to get proper feedback from qdisc and
NIC layers.
We use skb->sk to
A) control amount of bytes/packets queued on behalf of a socket, but
prior vxlan code did the skb->sk transfert without any limit/control
on vxlan socket sk_sndbuf.
B) security purposes (as selinux) or netfilter uses, and I do not think
anything is prepared to handle vxlan stacked case in this area.
By not changing ownership, vxlan tunnels behave like other tunnels.
As Stephen mentioned, we might do the same change in L2TP.

The existing serial state notification handling expected older Option
devices, having a hardcoded assumption that the Modem port was always
USB interface #2. That isn't true for devices from the past few years.
hso_serial_state_notification is a local cache of a USB Communications
Interface Class SERIAL_STATE notification from the device, and the
USB CDC specification (section 6.3, table 67 "Class-Specific Notifications")
defines wIndex as the USB interface the event applies to. For hso
devices this will always be the Modem port, as the Modem port is the
only port which is set up to receive them by the driver.
So instead of always expecting USB interface #2, instead validate the
notification with the actual USB interface number of the Modem port.

Proportional Integral controller Enhanced (PIE) is a scheduler to address the
bufferbloat problem.
>From the IETF draft below:
" Bufferbloat is a phenomenon where excess buffers in the network cause high
latency and jitter. As more and more interactive applications (e.g. voice over
IP, real time video streaming and financial transactions) run in the Internet,
high latency and jitter degrade application performance. There is a pressing
need to design intelligent queue management schemes that can control latency and
jitter; and hence provide desirable quality of service to users.
We present here a lightweight design, PIE(Proportional Integral controller
Enhanced) that can effectively control the average queueing latency to a target
value. Simulation results, theoretical analysis and Linux testbed results have
shown that PIE can ensure low latency and achieve high link utilization under
various congestion situations. The design does not require per-packet
timestamp, so it incurs very small overhead and is simple enough to implement
in both hardware and software. "

Eric Leblond.
* Add the reject expression to nf_tables, this adds the missing TCP RST
support. It comes with an initial patch to refactor common code with
xt_NFQUEUE, again from Eric Leblond.
* Remove an unused variable assignment in nf_tables_dump_set(), from Michal
Nazarewicz.
* Remove the nft_meta_target code, now that Arturo added the set operation
to the meta expression, from me.
* Add help information for nf_tables to Kconfig, also from me.
* Allow to dump all sets by specifying NFPROTO_UNSPEC, similar feature is
available to other nf_tables objects, requested by Arturo, from me.
* Expose the table usage counter, so we can know how many chains are using
this table without dumping the list of chains, from Tomasz Bursztyka.

Intel Wired LAN Driver Updates
This series contains updates to i40e only.
Majority of this series contains patches from Greg and Mitch to fix
up or add functionality to the PF/VF driver interactions. Notably,
a fix for SR-IOV VF port VLAN which resolved the problem of port VLAN
configurations not being persistent across VF driver loads and unloads
and enable/disable of the feature. Also do not enable the default port
on the VEB, which is designed only to bridge the PF to an Open vSwitch
or bridge. Another fix to resolve a possible memory corruption
condition where ARQ messages are written to random memory locations.
Fix a problem where the 'ip link show' command would display stale
link address information after the link address was set via the 'ip
link set' command.
Anjali provides several patches, one which saves information that can
be used while cleaning the Tx ring and useful in detecting Tx hangs.
Then provides a fixes to the admin queue shutdown function to ensure
we are shutting down the queue in the shutdown path and ensure ASQ is
alive before issuing the admin queue command.
Shannon provides a fix for get/update vsi params where the incorrect
struct was being used.

The driver wrongly assumes 16 EQs/vectors are available for each BE3 PF.
When SR-IOV is enabled, a BE3 PF can support only a max of 8 EQs.

The loopback test FW cmd may need upto 15 seconds to complete on
certain PHYs. This patch also fixes the name of the completion variable
used to synchronize FW cmd completions as it not used by the flashing
cmd alone anymore.
