BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
be found in two packages (versions): BCM53573 and BCM47189. It shares
some code with the Northstar family, but also requires some new quirks.

First of all there can be up to 2 Ethernet cores on this SoC. If that is
the case, they are connected to two different switch ports allowing some
more complex/optimized setups. It seems the second unit doesn't come
fully configured and requires some IRQ quirk.

Other than that only the first core is connected to the PHY. For the
second one we have to register fixed PHY (similarly to the Northstar),
otherwise generic PHY driver would get some invalid info.

This has been successfully tested on Tenda AC9 (BCM47189B0).

net: bridge: export vlan stats per-port with flags

This set adds the ability to export vlan stats per-port. Patch 01 makes
that possible by consolidating the bridge and port linkxstats calls. Then
patch 02 allows to dump the vlan entry flags in order to be able to
distinguish between bridge and port vlan entries when dumping the master
device vlan stats. That is needed because that call was implemented when
the stats API didn't have slave dumping capabilities and it dumps all vlan
stats (for both bridge and port entries). We also need it in order to print
the vlan flags when dumping the stats.

net_sched, flow_dissector, flower: Introduce vlan tag support

This patchset introduce vlan tag support to the flower classifier and the flow
dissector. In addition to adding vlan priority to act vlan.

The first 2 patches are dealing with flow-dissector:
 - The first patch is a fix, in case the vlan was already stripped from the
   skb, take it from skb->vlan_tci.
 - The second patch adds support for vlan priority.

The next 2 patches are dealing with flower:
 - The first patch is a fix, sets flow dissector 'used_keys' according to the
   mask value of each key.
 - The secound patch adds vlan tag support to the flower classifier, user space
   patches will be sent later to complete it.

The last patch adds vlan priority to act vlan since only vlan id is currently supported.

Changes from V1:
 - A new patch was added to this series "net_sched: flower: Avoid dissection of unmasked keys"
 - Adding u16 padding to struct flow_dissector_key_vlan
 - change flow_label field in struct flow_dissector_key_tags form 20 bits field to u32
 - Remove 'if (v->tcfv_push_prio)' check from tcf_vlan_dump function
 - Add support to un-stripped vlan skb and skb with multipale vlans in __skb_flow_dissect

dissector struct, flow_dissector_key_vlan which includes vlan tag

vlan_id and flow_label fields were under the same struct
(flow_dissector_key_tags). It was a convenient setting since struct
flow_dissector_key_tags is used by struct flow_keys and by setting
vlan_id and flow_label under the same struct, we get precisely 24 or 48

qdisc-hashtable fixes

The following two patches fix all the issues that have been reported
against the conversion of qdisc linked list to hashtable (currently in
net-next) so far.

First patch adjusts handling of singleton qdiscs to the new semantics, and
is rather straightforward.

The second patch, which fixes "cosmetic" issue of duplicate entries in the
qdisc dump for ingress qdiscs, is a little bit more hairy; I personally
would love to see all the already existing "if (ingress)"-like hacks go
away (by, let's say, introducing a general TCQ_F_? flag), but that's way
out of scope of this patchset (but already on my todo).

Thanks a lot to Daniel Borkmann and David Ahern for reporting the issues
and testing the patches promptly.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

tc_dump_qdisc() performs dumping of the per-device qdiscs in two phases;
first, the "standard" dev->qdisc is being dumped. Second, if there is/are
ingress queue(s), they are being dumped as well.

After conversion of netdevice's qdisc linked-list into hashtable, these
two sets are not in two disjunctive sets/lists any more, but are both
"reachable" directly from netdevice's hashtable. As a consequence, the
"full-depth" dump of the ingress qdiscs results in immediately hitting the
netdevice hashtable again, and duplicating the dump that has already been
performed for dev->qdisc.
What in fact needs to be dumped in case of ingress queue is "just" the
top-level ingress qdisc, as everything else has been dumped already.

Fix this by extending tc_dump_qdisc_root() in a way that it can be instructed
whether it should (while performing the "full" per-netdev qdisc dump) perform
the whole recursion, or just dump "additional" top-level (ingress) qdiscs
without performing any kind of recursion.

This fixes duplicate dumps such as

	qdisc mq 0: root
	qdisc pfifo_fast 0: parent :4 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

qdisc_match_from_root() is now iterating over per-netdevice qdisc
hashtable instead of going through a linked-list of qdiscs (independently
on the actual underlying netdev), which was the case before the switch to
hashtable for qdiscs.

For singleton qdiscs, there is no underlying netdev associated though, and
therefore dumping a singleton qdisc will panic, as qdisc_dev(root) will
always be NULL.

Fix this by special-casing singleton qdiscs (those that don't have
underlying netdevice) and introduce immediate handling of those rather
than trying to go over an underlying netdevice. We're in the same
situation in tc_dump_qdisc_root() and tc_dump_tclass_root().

Ultimately, this will have to be slightly reworked so that we are actually
able to show singleton qdiscs (noop) in the dump properly; but we're not
currently doing that anyway, so no regression there, and better do this in
a gradual manner.

tipc: bearer and link improvements

The first commit makes it possible to set and check the 'blocked' state
of a bearer from the generic bearer layer. The second commit is a small
improvement to the link congestion mechanism.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

When a link is attempted woken up after congestion, it uses a different,
more generous criteria than when it was originally declared congested.
This has the effect that the link, and the sending process, sometimes
will be woken up unnecessarily, just to immediately return to congestion
when it turns out there is not not enough space in its send queue to
host the pending message. This is a waste of CPU cycles.

We now change the function link_prepare_wakeup() to use exactly the same
criteria as tipc_link_xmit(). However, since we are now excluding the
window limit from the wakeup calculation, and the current backlog limit
for the lowest level is too small to house even a single maximum-size
message, we have to expand this limit. We do this by evaluating an
alternative, minimum value during the setting of the importance limits.

In commit 5b7066c3 ("tipc: stricter filtering of packets in bearer
layer") we introduced a method of filtering out messages while a bearer
is being reset, to avoid that links may be re-created and come back in
working state while we are still in the process of shutting them down.

This solution works well, but is limited to only work with L2 media, which
is insufficient with the increasing use of UDP as carrier media.

We now replace this solution with a more generic one, by introducing a
new flag "up" in the generic struct tipc_bearer. This field will be set
and reset at the same locations as with the previous solution, while
the packet filtering is moved to the generic code for the sending side.
On the receiving side, the filtering is still done in media specific
code, but now including the UDP bearer.

Some of the platforms like zynqmp ultrascale+ has a
separate clock gate for the rx clock. Add an optional
rx_clk so that the clock can be enabled.

====================
40GbE Intel Wired LAN Driver Updates 2016-08-18

This series contains updates to i40e and i40evf only.

Wei Yongjun updates i40e to use list_move() instead of list_del() &
list_add() operations.

Anjali fixes an issue where the client->open call was not protected with
the client instance mutex, which allowed client->close to be called before
the open all completed.

Catherine makes sure that the VLAN count (and stats) gets reset to 0
after reset.

Jake provides two patches, first adds the needed rtnl lock around
i40evf_set_interrupt_capability() since i40evf_init_task() does not
hold the rtnl_lock.  Second fixes an issue where users could reduce
the number of channels (queues) below the current flow director
filter rules targets.

Dave fixes a problem where a static analysis tool generates a warning
so eliminating the irrelevant check and redundant assignment for the
value of enabled_tc.

Avinash fixes an sync issue where the iWARP device open is called
before the PCI register writes are completed, so ensure the register
writes complete before exiting the setup function.

Alan fixes a bug which causes RSS to continue to work after being
disabled.

Carolyn implements a feature change which allows using ethtool to set
RDD hash options using less than four parameters if desired.

Dan Carpenter cleans up a stray unlock.

Sridhar exposes the "trust" flag to userspace via ndo_get_vf_config().

This enables
	ip -d l
to indicate if trust is on or off for VFs.

We shifted the locking around a bit but forgot to delete this unlock so
now it can unlock twice.

Fixes: cd3be169 ('i40e: Move the mutex lock in i40e_client_unregister')
