Conntrack dump does not support kernel side filtering (only get exists,
but it returns only one entry. And user has to give a full valid tuple)

It means that userspace has to implement filtering after receiving many
irrelevant entries, consuming resources (conntrack table is sometimes
very huge, much more than a routing table for example).

This patch adds filtering in kernel side. To achieve this goal, we:

 * Add a new CTA_FILTER netlink attributes, actually a flag list to
   parametize filtering
 * Convert some *nlattr_to_tuple() functions, to allow a partial parsing
   of CTA_TUPLE_ORIG and CTA_TUPLE_REPLY (so nf_conntrack_tuple it not
   fully set)

Filtering is now possible on:
 * IP SRC/DST values
 * Ports for TCP and UDP flows
 * IMCP(v6) codes types and IDs

Filtering is done as an "AND" operator. For example, when flags
PROTO_SRC_PORT, PROTO_NUM and IP_SRC are sets, only entries matching all
values are dumped.

Changes since v1:
  Set NLM_F_DUMP_FILTERED in nlm flags if entries are filtered

Changes since v2:
  Move several constants to nf_internals.h
  Move a fix on netlink values check in a separate patch
  Add a check on not-supported flags
  Return EOPNOTSUPP if CDA_FILTER is set in ctnetlink_flush_conntrack
  (not yet implemented)
  Code style issues

Changes since v3:
  Fix compilation warning reported by kbuild test robot

Changes since v4:
  Fix a regression introduced in v3 (returned EINVAL for valid netlink
  messages without CTA_MARK)

Changes since v5:
  Change definition of CTA_FILTER_F_ALL
  Fix a regression when CTA_TUPLE_ZONE is not set

The ocelot core library is written with the idea in mind that the VLAN
table is populated by the bridge. Otherwise, not even a sane default
pvid is provided: in standalone mode, the default pvid is 0, and the
core expects the bridge layer to change it to 1.

So without this patch, the VLAN table is completely empty at the end of
the commands below, and traffic is broken as a result:

ip link add dev br0 type bridge vlan_filtering 0 && ip link set dev br0 up
for eth in $(ls /sys/bus/pci/devices/0000\:00\:00.5/net/); do

This patch set contains another set of small changes in mlxsw trap

The device has a trap for IPv6 packets that need be routed and have a
unicast link-local destination IP (i.e., fe80::/10). This allows mlxsw
to ignore link-local routes, as the packets will be trapped to the CPU
in any case.

However, since link-local routes are not programmed, it is possible for
routed packets to hit the default route which might also be programmed
to trap packets. This means that packets with a link-local destination
IP might be trapped for the wrong reason.

To overcome this, allow programming link-local prefix routes (usually
one fe80::/64 per-table), so that the packets will be forwarded until
reaching the link-local trap.

Bidirectional Forwarding Detection (BFD) provides "low-overhead,
short-duration detection of failures in the path between adjacent
forwarding engines" (RFC 5880).

This is accomplished by exchanging BFD packets between the two
forwarding engines. Up until now these packets were trapped via the
general local delivery (i.e., IP2ME) trap which also traps a lot of
other packets that are not as time-sensitive as BFD packets.

Expose dedicated traps for BFD packets so that user space could

As explained in commit e6125230 ("mlxsw: spectrum_trap: Introduce

pass as less packets as possible to the CPU.

The identifier of this policer is currently set according to the maximum
number of used trap groups, but this is fragile: On Spectrum-1 the
maximum number of policers is less than the maximum number of trap
groups, which might result in an invalid policer identifier in case the
number of used trap groups grows beyond the policer limit.

When a packet enters the device it is classified to a filtering
identifier (FID) based on the ingress port and VLAN. The FID miss trap
is used to trap packets for which a FID could not be found.

In mlxsw this trap should only be triggered when a port is enslaved to
an OVS bridge and a matching ACL rule could not be found, so as to
trigger learning.

These packets are therefore completely unrelated to packets hitting

Split the ACL trap to a separate group with its own policer. Use a
higher priority for these traps than for traps using mirror action

net: ethernet: fec: move GPR register offset and bit into DT

The commit da722186 (net: fec: set GPR bit on suspend by
DT configuration) set the GPR reigster offset and bit in driver
for wol feature support.

It brings trouble to enable wol feature on imx6sx/imx6ul/imx7d
platforms that have multiple ethernet instances with different
GPR bit for stop mode control. So the patch set is to move GPR
register offset and bit define into DT, and enable imx6q/imx6dl
imx6qp/imx6sx/imx6ul/imx7d stop mode support.

Currently, below NXP i.MX boards support wol:
- imx6q/imx6dl/imx6qp sabresd
- imx6sx sabreauto
- imx7d sdb

imx6q/imx6dl/imx6qp sabresd board dts file miss the property
"fsl,magic-packet;", so patch#4 is to add the property for stop
mode support.

v1 -> v2:
 - driver: switch back to store the quirks bitmask in driver_data
 - dt-bindings: rename 'gpr' property string to 'fsl,stop-mode'
 - imx6/7 dtsi: add imx6sx/imx6ul/imx7d ethernet stop mode property
v2 -> v3:
 - driver: suggested by Sascha Hauer, use a struct fec_devinfo for
   abstracting differences between different hardware variants,
   it can give more freedom to describe the differences.
 - imx6/7 dtsi: correct one typo pointed out by Andrew.
