For Internet Protocol version 6 (IPv6) [RFC2460], the counterpart of
the ICMP destination unreachable message of code 0 (net unreachable)
and of code 1 (host unreachable) is the ICMPv6 destination
unreachable message of code 0 (no route to destination) [RFC4443].
As with IPv4, a router should generate an ICMPv6 destination
unreachable message of code 0 in response to a packet that cannot be
delivered to its destination address because it lacks a matching
entry in its routing table.

This patch adds a field to the tls rx offload context which enables
drivers to force a send_resync call.
This field can be used by drivers to request a resync at the next
possible tls record. It is beneficial for hardware that provides the
resync sequence number asynchronously. In such cases, the packet that
triggered the resync does not contain the information required for a
resync. Instead, the driver requests resync for all the following
TLS record until the asynchronous notification with the resync request
TCP sequence arrives.
A following series for mlx5e ConnectX-6DX TLS RX offload support will
use this mechanism.

This patch reworks the MRP netlink interface. Before, each attribute
represented a binary structure which made it hard to be extended.
Therefore update the MRP netlink interface such that each existing
attribute to be a nested attribute which contains the fields of the
binary structures.
In this way the MRP netlink interface can be extended without breaking
the backwards compatibility. It is also using strict checking for
attributes under the MRP top attribute.

There is a recurring pattern throughout some of the PHY code converting

With struct flow_dissector_key_mpls now recording the first
FLOW_DIS_MPLS_MAX labels, we can extend Flower to filter on any of
these LSEs independently.
In order to avoid creating new netlink attributes for every possible
depth, let's define a new TCA_FLOWER_KEY_MPLS_OPTS nested attribute
that contains the list of LSEs to match. Each LSE is represented by
another attribute, TCA_FLOWER_KEY_MPLS_OPTS_LSE, which then contains
the attributes representing the depth and the MPLS fields to match at
this depth (label, TTL, etc.).
For each MPLS field, the mask is always set to all-ones, as this is
what the original API did. We could allow user configurable masks in
the future if there is demand for more flexibility.
The new API also allows to only specify an LSE depth. In that case,
Flower only verifies that the MPLS label stack depth is greater or
equal to the provided depth (that is, an LSE exists at this depth).
Filters that only match on one (or more) fields of the first LSE are
dumped using the old netlink attributes, to avoid confusing user space
programs that don't understand the new API.

The current MPLS dissector only parses the first MPLS Label Stack
Entry (second LSE can be parsed too, but only to set a key_id).
This patch adds the possibility to parse several LSEs by making
__skb_flow_dissect_mpls() return FLOW_DISSECT_RET_PROTO_AGAIN as long
as the Bottom Of Stack bit hasn't been seen, up to a maximum of
FLOW_DIS_MPLS_MAX entries.
FLOW_DIS_MPLS_MAX is arbitrarily set to 7. This should be enough for
many practical purposes, without wasting too much space.
To record the parsed values, flow_dissector_key_mpls is modified to
store an array of stack entries, instead of just the values of the
first one. A bit field, "used_lses", is also added to keep track of
the LSEs that have been set. The objective is to avoid defining a
new FLOW_DISSECTOR_KEY_MPLS_XX for each level of the MPLS stack.
TC flower is adapted for the new struct flow_dissector_key_mpls layout.
Matching on several MPLS Label Stack Entries will be added in the next
patch.
The NFP and MLX5 drivers are also adapted: nfp_flower_compile_mac() and
mlx5's parse_tunnel() now verify that the rule only uses the first LSE
and fail if it doesn't.
Finally, the behaviour of the FLOW_DISSECTOR_KEY_MPLS_ENTROPY key is
slightly modified. Instead of recording the first Entropy Label, it
now records the last one. This shouldn't have any consequences since
there doesn't seem to have any user of FLOW_DISSECTOR_KEY_MPLS_ENTROPY
in the tree. We'd probably better do a hash of all parsed MPLS labels
instead (excluding reserved labels) anyway. That'd give better entropy
and would probably also simplify the code. But that's not the purpose
of this patch, so I'm keeping that as a future possible improvement.

100GbE Intel Wired LAN Driver Updates 2020-05-22
This series contains updates to virtchnl and the ice driver.
Geert Uytterhoeven fixes a data structure alignment issue in the
virtchnl structures.
Henry adds Flow Director support which allows for the redirection on
ntuple rules over six patches. Initially Henry adds the initial
infrastructure for Flow Director, and then later adds IPv4 and IPv6
support, as well as being able to display the ntuple rules.
Bret add Accelerated Receive Flow Steering (aRFS) support which is used
to steer receive flows to a specific queue. Fixes a transmit timeout
when the VF link transitions from up/down/up because the transmit and
receive queue interrupts are not enabled as part of VF's link up. Fixed
an issue when the default VF LAN address is changed and after reset the
PF will attempt to add the new MAC, which fails because it already
exists. This causes the VF to be disabled completely until it is removed
and enabled via sysfs.
Anirudh (Ani) makes a fix where the ice driver needs to call set_mac_cfg
to enable jumbo frames, so ensure it gets called during initialization
and after reset. Fix bad register reads during a register dump in
ethtool by removing the bad registers.
Paul fixes an issue where the receive Malicious Driver Detection (MDD)
auto reset message was not being logged because it occurred after the VF
reset.
Victor adds a check for compatibility between the Dynamic Device
Personalization (DDP) package and the NIC firmware to ensure that
everything aligns.
Jesse fixes a administrative queue string call with the appropriate
error reporting variable. Also fixed the loop variables that are
comparing or assigning signed against unsigned values.
