Ido Schimmel e3ea973159 ipv6: fib_rules: Check if rule is a default rule
As explained in commit 3c71006d15 ("ipv4: fib_rules: Check if rule is
a default rule"), drivers supporting IPv6 FIB offload need to be able to
sanitize the rules they don't support and potentially flush their
tables.

Add an IPv6 helper to check if a FIB rule is a default rule.

Ido Schimmel 1b2a444085 net: fib_rules: Implement notification logic in core
Unlike the routing tables, the FIB rules share a common core, so instead
of replicating the same logic for each address family we can simply dump
the rules and send notifications from the core itself.

To protect the integrity of the dump, a rules-specific sequence counter
is added for each address family and incremented whenever a rule is
added or deleted (under RTNL).

Ido Schimmel 04b1d4e50e net: core: Make the FIB notification chain generic
The FIB notification chain is currently soley used by IPv4 code.
However, we're going to introduce IPv6 FIB offload support, which
requires these notification as well.

As explained in commit c3852ef7f2 ("ipv4: fib: Replay events when
registering FIB notifier"), upon registration to the chain, the callee
receives a full dump of the FIB tables and rules by traversing all the
net namespaces. The integrity of the dump is ensured by a per-namespace
sequence counter that is incremented whenever a change to the tables or
rules occurs.

In order to allow more address families to use the chain, each family is
expected to register its fib_notifier_ops in its pernet init. These
operations allow the common code to read the family's sequence counter
as well as dump its tables and rules in the given net namespace.

Additionally, a 'family' parameter is added to sent notifications, so
that listeners could distinguish between the different families.

Implement the common code that allows listeners to register to the chain
and for address families to register their fib_notifier_ops. Subsequent
patches will implement these operations in IPv6.

In the future, ipmr and ip6mr will be extended to provide these
notifications as well.

Thomas Petazzoni says:

====================
net: mvpp2: add TX interrupts support

So far, the mvpp2 driver was using an hrtimer to handle TX
completion. This patch series adds support for using TX interrupts
(for each CPU) on PPv2.2, the variant of the IP used on Marvell Armada
7K/8K.

Dave: this version can be applied right away, it no longer depends on
Antoine's patch series. Antoine series had some comments, so he will
have to respin later on. Therefore, let's merge this smaller patch
series first.

Changes since v1:

 - Rebased on top of net-next, instead of on top of Antoine's series.

 - Removed the Device Tree patch, as it shouldn't go through the net
   tree.

Thomas Petazzoni 5d3ecb24b5 dt-bindings: net: marvell-pp2: update interrupt-names with TX interrupts
The PPv2.2 unit has several interrupts used for TX completion
notification. This commit updates the Device Tree binding describing
this HW block to mention such interrupts.

While at it, we update the example to use a recent Device Tree
example, that uses interrupts going through the ICU, and not to the
GIC directly.

Thomas Petazzoni 213f428f50 net: mvpp2: add support for TX interrupts and RX queue distribution modes
This commit adds the support for two related features:

 - Support for TX interrupts, with one interrupt for each CPU

 - Support for different RX queue distribution modes
   MVPP2_QDIST_SINGLE_MODE where a single interrupt, shared by all
   CPUs, receives the RX events, and MVPP2_QDIST_MULTI_MODE, where the
   per-CPU interrupts used for TX events are also used for RX events.

Since additional interrupts are needed, an update to the Device Tree
binding is needed. However, backward compatibility is preserved with
the old Device Tree binding, by gracefully degrading to the original
behavior, with only one RX interrupt, and TX completion being handled
by an hrtimer.

Thomas Petazzoni 591f4cfab3 net: mvpp2: introduce queue_vector concept
In preparation to the introduction of TX interrupts and improved RX
queue distribution, this commit introduces the concept of "queue
vector". A queue vector represents a number of RX and/or TX queues,
and an associated NAPI instance and interrupt.

This commit currently only creates a single queue_vector, so there are
no changes in behavior, but it paves the way for additional
queue_vector in the next commits.

Thomas Petazzoni df089aa0ac net: mvpp2: move from cpu-centric naming to "software thread" naming
The PPv2.2 IP has a concept of "software thread", with all registers
of the PPv2.2 mapped 8 times, for concurrent accesses by 8 "software
threads". In addition, interrupts on RX queues are associated to such
"software thread".

For most cases, we map a "software thread" to the more conventional
concept of CPU, but we will soon have one exception: we will have a
model where we have one TX interrupt per CPU (each using one software
thread), and all RX events mapped to another software thread
(associated to another interrupt).

In preparation for this change, it makes sense to change the naming
from MVPP2_MAX_CPUS to MVPP2_MAX_THREADS, and plan for 8 software
threads instead of 4 currently.

Thomas Petazzoni 09f8397553 net: mvpp2: introduce per-port nrxqs/ntxqs variables
Currently, the global variables rxq_number and txq_number hold the
number of per-port TXQs and RXQs. Until now, such numbers were
constant regardless of the driver configuration. As we are going to
introduce different modes for TX and RX queues, these numbers will
depend on the configuration (PPv2.1 vs. PPv2.2, exact queue
distribution logic).

Therefore, as a preparation, we move the number of RXQs and TXQs in
the 'struct mvpp2_port' structure, next to the RXQs and TXQs
descriptor arrays.

For now, they remain initialized to the same default values as
rxq_number/txq_number used to be initialized, but this will change in
future commits.

The only non-mechanical change in this patch is that the check to
verify hardware constraints on the number of RXQs and TXQs is moved
from mvpp2_probe() to mvpp2_port_probe(), since it's now in
mvpp2_port_probe() that we initialize the per-port count of RXQ and
TXQ.

Salil Mehta says:

====================
Hisilicon Network Subsystem 3 Ethernet Driver

This patch-set contains the support of the HNS3 (Hisilicon Network Subsystem 3)
Ethernet driver for hip08 family of SoCs and future upcoming SoCs.

Hisilicon's new hip08 SoCs have integrated ethernet based on PCI Express and
hence there was a need of new driver over the previous HNS driver which is
already part of the Linux mainline. This new driver is NOT backward
compatible with HNS.

This current driver is meant to control the Physical Function and there would
soon be a support of a separate driver for Virtual Function once this base PF
driver has been accepted. Also, this driver is the ongoing development work and
HNS3 Ethernet driver would be incrementally enhanced with more new features.

Neal Cardwell d06c3583c2 tcp: remove extra POLL_OUT added for finished active connect()
Commit 45f119bf93 ("tcp: remove header prediction") introduced a
minor bug: the sk_state_change() and sk_wake_async() notifications for
a completed active connection happen twice: once in this new spot
inside tcp_finish_connect() and once in the existing code in
tcp_rcv_synsent_state_process() immediately after it calls
tcp_finish_connect(). This commit remoes the duplicate POLL_OUT
notifications.

Vivien Didelot 3a8f6f874f net: dsa: bcm_sf2: dst in not an array
It's been a while now since ds->dst is not an array anymore, but a
simple pointer to a dsa_switch_tree.

Fortunately, SF2 does not support multi-chip and thus ds->index is
always 0.

This patch substitutes 'ds->dst[ds->index].' with 'ds->dst->'.

Sowmini Varadhan 840df162b3 rds: reduce memory footprint for RDS when transport is RDMA
RDS over IB does not use multipath RDS, so the array
of additional rds_conn_path structures is always superfluous
in this case. Reduce the memory footprint of the rds module
by making this a dynamic allocation predicated on whether
the transport is mp_capable.
