Commit ccfdec908922 ("macsec: Add support for GCM-AES-256 cipher suite")
changed a few values in the uapi headers for MACsec.
Because of existing userspace implementations, we need to preserve the
value of MACSEC_DEFAULT_CIPHER_ID. Not doing that resulted in
wpa_supplicant segfaults when a secure channel was created using the
default cipher. Thus, swap MACSEC_DEFAULT_CIPHER_{ID,ALT} back to their
original values.
Changing the maximum length of the MACSEC_SA_ATTR_KEY attribute is
unnecessary, as the previous value (MACSEC_MAX_KEY_LEN, which was 128B)
is large enough to carry 32-bytes keys. This patch reverts
MACSEC_MAX_KEY_LEN to 128B and restores the old length check on
MACSEC_SA_ATTR_KEY.

The main purpose of this patch is adding a way of checking per-queue stats.
It's useful to debug performance problems on multiqueue environment.
$ ethtool -S ens10
NIC statistics:
rx_queue_0_packets: 2090408
rx_queue_0_bytes: 3164825094
rx_queue_1_packets: 2082531
rx_queue_1_bytes: 3152932314
tx_queue_0_packets: 2770841
tx_queue_0_bytes: 4194955474
tx_queue_1_packets: 3084697
tx_queue_1_bytes: 4670196372
This change converts existing per-cpu stats structure into per-queue one.
This should not impact on performance since each queue counter is not
updated concurrently by multiple cpus.
Performance numbers:
- Guest has 2 vcpus and 2 queues
- Guest runs netserver
- Host runs 100-flow super_netperf

This patch introduces an alternative way of obtaining resources - via
ACPI tables provided by firmware. Enabling coexistence with the DT
support, in addition to the OF_*->device_*/fwnode_* API replacement,
required following steps to be taken:
* Add mvpp2_acpi_match table
* Omit clock configuration and obtain tclk from the property - in ACPI
world, the firmware is responsible for clock maintenance.
* Disable comphy and syscon handling as they are not available for ACPI.
* Modify way of obtaining interrupts - use newly introduced
fwnode_irq_get() routine
* Until proper MDIO bus and PHY handling with ACPI is established in the
kernel, use only link interrupts feature in the driver. For the RGMII
port it results in depending on GMAC settings done during firmware
stage.
* When booting with ACPI MVPP2_QDIST_MULTI_MODE is picked by
default, as there is no need to keep any kind of the backward
compatibility.
Moreover, a memory region used by mvmdio driver is usually placed in
the middle of the address space of the PP2 network controller.
The MDIO base address is obtained without requesting memory region
(by devm_ioremap() call) in mvmdio.c, later overlapping resources are
requested by the network driver, which is responsible for avoiding
a concurrent access.
In case the MDIO memory region is declared in the ACPI, it can
already appear as 'in-use' in the OS. Because it is overlapped by second
region of the network controller, make sure it is released, before
requesting it again. The care is taken by mvpp2 driver to avoid
concurrent access to this memory region.

'port_count' field of the mvpp2 structure holds an overall amount
of available ports, based on DT nodes status. In order to be prepared
to support other HW description, obtain the value by incrementing it
upon each successful port initialization. This allowed for simplifying
port indexing in the controller's private array, whose size is now not
dynamically allocated, but fixed to MVPP2_MAX_PORTS.
This patch simplifies creating and filling list of enabled ports and
is a part of the preparation for adding ACPI support in the mvpp2 driver.

Until now there were two very similar functions allowing
to get Linux IRQ number from ACPI handle (acpi_irq_get())
and OF node (of_irq_get()). The first one appeared to be used
only as a subroutine of platform_irq_get(), which (in the generic
code) limited IRQ obtaining from _CRS method only to nodes
associated to kernel's struct platform_device.
This patch introduces a new helper routine - fwnode_irq_get(),
which allows to get the IRQ number directly from the fwnode
to be used as common for OF/ACPI worlds. It is usable not
only for the parents fwnodes, but also for the child nodes
comprising their own _CRS methods with interrupts description.
In order to be able o satisfy compilation with !CONFIG_ACPI
and also simplify the new code, introduce a helper macro
(ACPI_HANDLE_FWNODE), with which it is possible to reach
an ACPI handle directly from its fwnode.

Until now there were two almost identical functions for

mlxsw: spectrum_router: Optimize LPM trees
Ido says:
This set tries to optimize the structure of the LPM trees used for route
lookup by avoiding lookups that are guaranteed not to return a result.
This is done by making sure only used prefix lengths are present in the
tree.

In commit fc922bb0dd94 ("mlxsw: spectrum_router: Use one LPM tree for
all virtual routers") I tried to make sure only used prefix lengths are
present in the LPM tree shared between all virtual routers.
However, this optimization had to be removed in commit a69518cf0b4c
("mlxsw: spectrum_router: Avoid expensive lookup during route removal"),
since determining the used prefix lengths required us to traverse all
the active virtual routers, which could result in a hung task depending
on the number of VRFs and whether routes were removed due to abort or
not.
Re-introduce the optimization by moving the prefix usage accounting from
the virtual routers to the LPM tree, as this accounting is only used in
order to determine the tree's structure.
To make the sharing of the trees more explicit, the two trees (for IPv4
and IPv6) are stored in the shared router struct and upon the creation
of a virtual router it is immediately bound to both.

Currently, each FIB (IPv4 / IPv6) in a virtual router holds a prefix
usage that is used to choose a matching LPM tree, but also to check if
the FIB is empty, so that the LPM tree could be unbound.
Next patches will remove the reliance on the per-FIB prefix usage for
LPM tree matching. Keeping it only to check if the FIB is empty is a
waste, since we can use the nodes ({Prefix, Length}) list instead.

First six patches of this series further enhances the mlx5 hairpin support.
The first two patches deal with using different hairpin instances
for flows whose packets have different priorities to align with the port
TX QoS model. The next four patches allow us to do HW spreading
of flows over a set of hairpin pairs using RSS. The last two patches
change the driver to also set the size of the HW hairpin queues.
========
Next four patches from Eran Ben Elisha <eranbe@mellanox.com>:
Add more debug data for TX timeout handling, and further enhance and optimize
TX timeout handling upon lost interrupts, which adds a mechanism for explicitly
polling EQ in case of a TX timeout in order to recover from a lost interrupt.
If this is not the case (no pending EQEs), perform a channels full recovery as
usual.

nf_tables that saves us 500 LoC, allow raw table registration before
defragmentation, conversion of the SNMP helper to use the ASN.1 code
generator, unique 64-bit handle for all nf_tables objects and fixes to
address fallout from previous nf-next batch. More specifically, they
are:
1) Seven patches to remove family abstraction layer (struct nft_af_info)
in nf_tables, this simplifies our codebase and it saves us 64 bytes per
net namespace.
2) Add IPv6 segment routing header matching for ip6tables, from Ahmed
Abdelsalam.
3) Allow to register iptable_raw table before defragmentation, some
people do not want to waste cycles on defragmenting traffic that is
going to be dropped, hence add a new module parameter to enable this
behaviour in iptables and ip6tables. From Subash Abhinov
Kasiviswanathan. This patch needed a couple of follow up patches to
get things tidy from Arnd Bergmann.
4) SNMP helper uses the ASN.1 code generator, from Taehee Yoo. Several
patches for this helper to prepare this change are also part of this
patch series.
5) Add 64-bit handles to uniquely objects in nf_tables, from Harsha
Sharma.
6) Remove log message that several netfilter subsystems print at
boot/load time.
7) Restore x_tables module autoloading, that got broken in a previous
patch to allow singleton NAT hook callback registration per hook
spot, from Florian Westphal. Moreover, return EBUSY to report that
the singleton NAT hook slot is already in instead.
8) Several fixes for the new nf_tables flowtable representation,
including incorrect error check after nf_tables_flowtable_lookup(),
missing Kconfig dependencies that lead to build breakage and missing
initialization of priority and hooknum in flowtable object.
9) Missing NETFILTER_FAMILY_ARP dependency in Kconfig for the clusterip
target. This is due to recent updates in the core to shrink the hook
array size and compile it out if no specific family is enabled via
.config file. Patch from Florian Westphal.
10) Remove duplicated include header files, from Wei Yongjun.
11) Sparse warning fix for the NFPROTO_INET handling from the core
due to missing static function definition, also from Wei Yongjun.
12) Restore ICMPv6 Parameter Problem error reporting when
defragmentation fails, from Subash Abhinov Kasiviswanathan.
13) Remove obsolete owner field initialization from struct
file_operations, patch from Alexey Dobriyan.
14) Use boolean datatype where needed in the Netfilter codebase, from
Gustavo A. R. Silva.
15) Remove double semicolon in dynset nf_tables expression, from
Luis de Bethencourt.

====================
pull-request: bpf-next 2018-01-19
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) bpf array map HW offload, from Jakub.
2) support for bpf_get_next_key() for LPM map, from Yonghong.
3) test_verifier now runs loaded programs, from Alexei.
4) xdp cpumap monitoring, from Jesper.
5) variety of tests, cleanups and small x64 JIT optimization, from Daniel.
6) user space can now retrieve HW JITed program, from Jiong.
Note there is a minor conflict between Russell's arm32 JIT fixes
and removal of bpf_jit_enable variable by Daniel which should
be resolved by keeping Russell's comment and removing that variable.

The BPF verifier conflict was some minor contextual issue.
The TUN conflict was less trivial. Cong Wang fixed a memory leak of
tfile->tx_array in 'net'. This is an skb_array. But meanwhile in
net-next tun changed tfile->tx_arry into tfile->tx_ring which is a
ptr_ring.
