Updates highlights:
1) From Vu Pham (8): Support VM traffics failover with bonded VF
representors and e-switch egress/ingress ACLs
This series introduce the support for Virtual Machine running I/O
traffic over direct/fast VF path and failing over to slower
paravirtualized path using the following features:

Summary:
--------
Problem statement:
------------------
Currently in above topology, when netfailover device is configured using
VFs and eswitch VF representors, and when traffic fails over to stand-by
VF which is exposed using macvtap device to guest VM, eswitch fails to
switch the traffic to the stand-by VF representor. This occurs because
there is no knowledge at eswitch level of the stand-by representor
device.
Solution:
---------
Using standard bonding driver, a bond netdevice is created over VF
representor device which is used for offloading tc rules.
Two VF representors are bonded together, one for the passthrough VF
device and another one for the stand-by VF device.
With this solution, mlx5 driver listens to the failover events
occuring at the bond device level to failover traffic to either of
the active VF representor of the bond.
a. VM with netfailover device of VF pass-thru (PT) device and virtio-net
paravirtualized device with same MAC-address to handle failover
traffics at VM level.
b. Host bond is active-standby mode, with the lower devices being the VM
VF PT representor, and the representor of the 2nd VF to handle
failover traffics at Hypervisor/V-Switch OVS level.
- During the steady state (fast datapath): set the bond active
device to be the VM PT VF representor.
- During failover: apply bond failover to the second VF representor
device which connects to the VM non-accelerated path.
c. E-Switch ingress/egress ACL tables to support failover traffics at
E-Switch level
I. E-Switch egress ACL with forward-to-vport rule:
- By default, eswitch vport egress acl forward packets to its
counterpart NIC vport.
- During port failover, the egress acl forward-to-vport rule will
be added to e-switch vport of passive/in-active slave VF
representor
to forward packets to other e-switch vport ie. the active slave
representor's e-switch vport to handle egress "failover"
traffics.
- Using lower change netdev event to detect a representor is a
lower
dev (slave) of bond and becomes active, adding egress acl
forward-to-vport rule of all other slave netdevs to forward to
this
representor's vport.
- Using upper change netdev event to detect a representor unslaving
from bond device to delete its vport's egress acl forward-to-vport
rule.
II. E-Switch ingress ACL metadata reg_c for match
- Bonded representors' vorts sharing tc block have the same
root ingress acl table and a unique metadata for match.
- Traffics from both representors's vports will be tagged with same
unique metadata reg_c.
- Using upper change netdev event to detect a representor
enslaving/unslaving from bond device to setup shared root ingress
acl and unique metadata.
2) From Alex Vesker (2): Slpit RX and TX lock for parallel rule insertion in
software steering
3) Eli Britstein (2): Optimize performance for IPv4/IPv6 ethertype use the HW
ip_version register rather than parsing eth frames for ethertype.

Make tcp_ld_RTO_revert() helper available to IPv6, and
implement RFC 6069 :
Quoting this RFC :
3. Connectivity Disruption Indication
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.

SJA1105, being AVB/TSN switches, provide hardware assist for the
Credit-Based Shaper as described in the IEEE 8021Q-2018 document.
First generation has 10 shapers, freely assignable to any of the 4
external ports and 8 traffic classes, and second generation has 16
shapers.
The Credit-Based Shaper tables are accessed through the dynamic
reconfiguration interface, so we have to restore them manually after a
switch reset. The tables are backed up by the static config only on
P/Q/R/S, and we don't want to add custom code only for that family,
since the procedure that is in place now works for both.
Tested with the following commands:
data_rate_kbps=67000
port_transmit_rate_kbps=1000000
idleslope=$data_rate_kbps
sendslope=$(($idleslope - $port_transmit_rate_kbps))

Change the locking flow to support RX and TX locks, splitting
the single lock to two will allow inserting rules in parallel
for RX and TX parts of the FDB.
Locking the dr_domain will be done by locking the RX domain
and the TX domain locks, this is mostly used for control operations
on the dr_domain. When inserting rules for RX or TX the single
nic_doamin RX or TX lock will be used. Splitting the lock is safe since
RX and TX domains are logically separated from each other, shared
objects such the send-ring and memory pool are protected by locks.

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

success if the same rule/cookie is offloaded again to other slave

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.

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.

Resetting old qdisc on dev_queue->qdisc_sleeping in
dev_qdisc_reset() is redundant, because this qdisc,
even if not same with dev_queue->qdisc, is reset via
qdisc_put() right after calling dev_graft_qdisc() when
hitting refcnt 0.
This is very easy to observe with qdisc_reset() tracepoint
and stack traces.

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.

====================
tcp: tcp_v4_err() cleanups
This series is a followup of patch 239174945dac ("tcp: tcp_v4_err() icmp
skb is named icmp_skb").
Move the RFC 6069 code into a helper, and rename icmp_skb to standard
skb name so that tcp_v4_err() and tcp_v6_err() are using consistent names.

This essentially reverts 4d1a2d9ec1c1 ("Revert Backoff [v3]:
Rename skb to icmp_skb in tcp_v4_err()")
Now we have tcp_ld_RTO_revert() helper, we can use the usual
name for sk_buff parameter, so that tcp_v4_err() and
tcp_v6_err() use similar names.

RFC 6069 logic has been implemented for IPv4 only so far,
right in the middle of tcp_v4_err() and was error prone.
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.

When initializing CMDQ fails because of reset pending,
there is no hint for debugging, so adds a log for it.

Packets will not pass through MAC during app loopback.
Therefore, it is meaningless to enable MAC while doing
app loopback. This patch removes this unnecessary action.

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.

net: mscc: allow forwarding ioctl operations to attached PHYs
These two patches allow forwarding ioctl to the PHY MII implementation,
and support is added for offloading timestamping operations to
compatible attached PHYs.

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.
