d34eb2fcd0 net/mlx5e: Offload flow rules to active lower representor
When a bond device is created over one or more non uplink representors,
and when a flow rule is offloaded to such bond device, offload a rule
to the active lower device.

Assuming that this is active-backup lag, the rules should be offloaded
to the active lower device which is the representor of the direct
path (not the failover).

553f932838 net/mlx5e: Support tc block sharing for representors
Currently offloading a rule over a tc block shared by multiple
representors fails because an e-switch global hashtable to keep
the mapping from tc cookies to mlx5e flow instances is used, and
tc block sharing offloads the same rule/cookie multiple times,
each time for different representor sharing the tc block.

Changing the implementation and behavior by acknowledging and returning
success if the same rule/cookie is offloaded again to other slave
representor sharing the tc block by setting, checking and comparing
the netdev that added the rule first.

7e51891a23 net/mlx5e: Use netdev events to set/del egress acl forward-to-vport rule
Register a notifier block to handle netdev events for bond device
of non-uplink representors to support eswitch vports bonding.

When a non-uplink representor is a lower dev (slave) of bond and
becomes active, adding egress acl forward-to-vport rule of all slave
netdevs (active + standby) to forward to this representor's vport. Use
change lower netdev event to do this.

Use change upper event to detect slave representor unslaved from lag
device to delete its vport egress acl forward rule if any.

bf773dc0e6 net/mlx5: E-Switch, Introduce APIs to enable egress acl forward-to-vport rule
By default, e-switch vport's egress acl just forward packets to its
counterpart NIC vport using existing egress acl table.

During port failover in bonding scenario where two VFs representors
are bonded, the egress acl forward-to-vport rule will be added to
the existing egress acl table of e-switch vport of passive/inactive
slave representor to forward packets to other NIC vport ie. the active
slave representor's NIC vport to handle egress "failover" traffic.

Enable egress acl and have APIs to create and destroy egress acl
forward-to-vport rule and group.

patch changes this number to match the number of receive queues.

The only difference between a few missing fixes applied to the SCTP
one is that TCP uses ->getpeername to get the remote address, while
SCTP uses kernel_getsockopt(.. SCTP_PRIMARY_ADDR).  But given that
getpeername is defined to return the primary address for sctp, there
doesn't seem to be any reason for the different way of quering the
peername, or all the code duplication.

b3ae2459f8 net/tls: Add force_resync for driver resync
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.

dev_qdisc_reset() is redundant, because this qdisc,
even if not same with dev_queue->qdisc, is reset via

This is very easy to observe with qdisc_reset() tracepoint
and stack traces.

70f5096533 net_sched: avoid resetting active qdisc for multiple times
Except for sch_mq and sch_mqprio, each dev queue points to the
same root qdisc, so when we reset the dev queues with
netdev_for_each_tx_queue() we end up resetting the same instance
of the root qdisc for multiple times.

Avoid this by checking the __QDISC_STATE_DEACTIVATED bit in
each iteration, so for sch_mq/sch_mqprio, we still reset all
of them like before, for the rest, we only reset it once.

Move this code to one helper, to make tcp_v4_err() more
readable and to eventually expand RFC 6069 to IPv6 in
the future.

Also perform sock_owned_by_user() check a bit sooner.

60c800c64d net: hns3: change the order of reinitializing RoCE and NIC client during reset
The HNS RDMA driver will support VF device later, whose
re-initialization should be done after PF's. This patch
changes the order of hclge_reset_prepare_up() and
hclge_notify_roce_client(), so that PF's RoCE client
will be reinitialized before VF's.

b2e118f638 net: mscc: allow offloading timestamping operations to the PHY
This patch adds support for offloading timestamping operations not only
to the Ocelot switch (as already supported) but to compatible PHYs.
When both the PHY and the Ocelot switch support timestamping operations,
the PHY implementation is chosen as the timestamp will happen closer to
the medium.

626a83238e net: dsa: felix: accept VLAN config regardless of bridge VLAN awareness state
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
	ip link set dev $eth master br0
	ip link set dev $eth up
done
ip link set dev br0 type bridge vlan_filtering 1

The tests create 100 x32 ecmp groups of ipv4 and ipv6 and then
dump them. On kernels without the fix, they will fail due
to data remnant during the dump.

20f6a05ef6 bridge: mrp: Rework the MRP netlink interface
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.
