Currently, we scan over all network namespaces at each received
discovery message in order to check if the sending peer might be
present in a host local namespaces.
This is unnecessary since we can assume that a peer will not change its
location during an established session.
We now improve the condition for this testing so that we don't perform
any redundant scans.

On 64bit arches, struct u64_stats_sync is empty and provides
no help against load/store tearing.
Using READ_ONCE()/WRITE_ONCE() would be needed.
But the update side would be slightly more expensive.
local64_t was defined so that we could use regular adds
in a manner which is atomic wrt IRQs.
However the u64_stats infra means we do not have to use
local64_t on 32bit arches since the syncp provides the needed

mlxsw: Add layer 3 devlink-trap support
This patch set from Amit adds support in mlxsw for layer 3 traps that
can report drops and exceptions via devlink-trap.
In a similar fashion to the existing layer 2 traps, these traps can send
packets to the CPU that were not routed as intended by the underlying
device.
The traps are divided between the two types detailed in devlink-trap
documentation: drops and exceptions. Unlike drops, packets received via
exception traps are also injected to the kernel's receive path, as they
are required for the correct functioning of the control plane. For
example, packets trapped due to TTL error must be injected to kernel's
receive path for traceroute to work properly.
Patch set overview:
Patch #1 adds the layer 3 drop traps to devlink along with their
documentation.
Patch #2 adds support for layer 3 drop traps in mlxsw.
Patches #3-#5 add selftests for layer 3 drop traps.
Patch #6 adds the layer 3 exception traps to devlink along with their
documentation.
Patches #7-#9 gradually add support for layer 3 exception traps in
mlxsw.
Patches #10-#12 add selftests for layer 3 exception traps.

Currently, mlxsw does not differentiate between these two cases of
routes with invalid nexthops:
1. Nexthops whose nexthop device is a mlxsw upper (has a RIF), but whose
neighbour could not be resolved
2. Nexthops whose nexthop device is not a mlxsw upper (e.g., management
interface)
Up until now this did not matter and mlxsw trapped packets for both
cases using the same trap ID. However, packets that should have been
routed in hardware (case 1), but incurred a problem are considered
exceptions and should be reported to the user. The two cases should
therefore be split between two different trap IDs.
Allocate a new adjacency entry during initialization and upon the
insertion of the first route with an invalid mlxsw nexthop, program this
entry to discard packets. Packets hitting this entry will be reported
using new trap ID - "DISCARD_ROUTER3".
In the future, the entry could be written during initialization, but
currently firmware requires a valid RIF, which is not available at this
stage.

Currently, packets that cannot be routed in hardware (e.g., nexthop
device is not upper of mlxsw), are trapped to the kernel for forwarding.
Such packets are trapped using "RTR_INGRESS0" trap. This trap also traps
packets that hit reject routes (e.g., "unreachable") so that the kernel
will generate the appropriate ICMP error message for them.
Subsequent patch will need to only report to devlink packets that hit a
reject route, which is impossible as long as "RTR_INGRESS0" is
overloaded like that.
Solve this by using "RTR_INGRESS1" trap for packets that hit reject
routes.
