mlx5-updates-2020-09-22

This series includes mlx5 updates

1) Add support for Connection Tracking offload in NIC mode.
   Supporting CT offload in NIC mode on Mellanox cards is useful for
   scenarios where the dual port NIC serves as a gateway between 2
   networks and forwards traffic between these networks.

   Since the traffic is not terminated on the host in this case,
   no use of SRIOV VFs and/or switchdev mode is required.

   Today Mellanox NIC cards already support offloading of packet forwarding
   between physical ports without going to the host so combining it with CT
   offloading allows users to create a gateway with forwarding and CT
   (Including NAT) offloading capabilities in non-switchdev mode.

   To support connection tracking in non-Switchdev mode (Single NIC mode),
   we need to make use of the current Connection tracking infrastructure
   implemented on top of E-Switch and the mlx5 generic flow table chains
   APIs, to make it work on non-Eswitch steering domain e.g. NIC RX domain,
   the following was performed:

 1.1) Refactor current flow steering chains infrastructure and
      updates TC nic mode implementation to use flow table chains.
 1.2) Refactor current Connection Tracking (CT) infrastructure to not
      assume E-switch backend, and make the CT layer agnostic to
      underlying steering mode (E-Switch/NIC)
 1.3) Plumbing to support CT offload in NIC mode.

2) Trivial code cleanups.

dpaa2-mac: add PCS support through the Lynx module

This patch set aims to add PCS support in the dpaa2-eth driver by
leveraging the Lynx PCS module.

The first two patches are some missing pieces: the first one adding
support for 10GBASER in Lynx PCS while the second one adds a new
function - of_mdio_find_device - which is helpful in retrieving the PCS
represented as a mdio_device.  The final patch adds the glue logic
between phylink and the Lynx PCS module: it retrieves the PCS
represented as an mdio_device and registers it to Lynx and phylink.
From that point on, any PCS callbacks are treated by Lynx, without
dpaa2-eth interaction.

needed in the dpaa2-eth driver since the only steps necessary are to
find the MDIO device representing the PCS, register it to the Lynx PCS
module and then let phylink know if its existence also.
After this, the PCS callbacks will be treated directly by Lynx, without
interraction from dpaa2-eth's part.

Currently, ocelot switchdev passes the skb directly to the function that
enqueues it to the list of skb's awaiting a TX timestamp. Whereas the
felix DSA driver first clones the skb, then passes the clone to this
queue.

This matters because in the case of felix, the common IRQ handler, which
is ocelot_get_txtstamp(), currently clones the clone, and frees the
original clone. This is useless and can be simplified by using
skb_complete_tx_timestamp() instead of skb_tstamp_tx().

net: dsa: b53: Configure VLANs while not filtering

These two patches allow the b53 driver which always configures its CPU
port as egress tagged to behave correctly with VLANs being always
configured whenever a port is added to a bridge.

Vladimir provides a patch that aligns the bridge with vlan_filtering=0
receive path to behave the same as vlan_filtering=1. Per discussion with
Nikolay, this behavior is deemed to be too DSA specific to be done in
the bridge proper.

This is a preliminary series for Vladimir to make
configure_vlan_while_filtering the default behavior for all DSA drivers
in the future.

Thanks!

Changes in v3:

- added Vladimir's Acked-by tag to patch #2
- removed unnecessary if_vlan.h inclusion in patch #2
- reworded commit message to be accurate with the code changes

Changes in v2:

- moved the call to dsa_untag_bridge_pvid() into net/dsa/tag_brcm.c

====================

Update the B53 driver to support VLANs while not filtering. This
requires us to enable VLAN globally within the switch upon driver
initial configuration (dev->vlan_enabled).

We also need to remove the code that dealt with PVID re-configuration in
b53_vlan_filtering() since that function worked under the assumption
that it would only be called to make a bridge VLAN filtering, or not
filtering, and we would attempt to move the port's PVID accordingly.

Now that VLANs are programmed all the time, even in the case of a
non-VLAN filtering bridge, we would be programming a default_pvid for
the bridged switch ports.

We need the DSA receive path to pop the VLAN tag if it is the bridge's
default_pvid because the CPU port is always programmed tagged in the
programmed VLANs. In order to do so we utilize the
dsa_untag_bridge_pvid() helper introduced in the commit before within
net/dsa/tag_brcm.c.

Currently the bridge untags VLANs present in its VLAN groups in
__allowed_ingress() only when VLAN filtering is enabled.

But when a skb is seen on the RX path as tagged with the bridge's pvid,
and that bridge has vlan_filtering=0, and there isn't any 8021q upper
with that VLAN either, then we have a problem. The bridge will not untag
it (since it is supposed to remain VLAN-unaware), and pvid-tagged
communication will be broken.

There are 2 situations where we can end up like that:

1. When installing a pvid in egress-tagged mode, like this:

ip link add dev br0 type bridge vlan_filtering 0
ip link set swp0 master br0
bridge vlan del dev swp0 vid 1
bridge vlan add dev swp0 vid 1 pvid

This happens because DSA configures the VLAN membership of the CPU port
using the same flags as swp0 (in this case "pvid and not untagged"), in
an attempt to copy the frame as-is from ingress to the CPU.

However, in this case, the packet may arrive untagged on ingress, it
will be pvid-tagged by the ingress port, and will be sent as
egress-tagged towards the CPU. Otherwise stated, the CPU will see a VLAN
tag where there was none to speak of on ingress.

When vlan_filtering is 1, this is not a problem, as stated in the first
paragraph, because __allowed_ingress() will pop it. But currently, when
vlan_filtering is 0 and we have such a VLAN configuration, we need an
8021q upper (br0.1) to be able to ping over that VLAN, which is not
symmetrical with the vlan_filtering=1 case, and therefore, confusing for
users.

Basically what DSA attempts to do is simply an approximation: try to
copy the skb with (or without) the same VLAN all the way up to the CPU.
But DSA drivers treat CPU port VLAN membership in various ways (which is
a good segue into situation 2). And some of those drivers simply tell
the CPU port to copy the frame unmodified, which is the golden standard
when it comes to VLAN processing (therefore, any driver which can
configure the hardware to do that, should do that, and discard the VLAN
flags requested by DSA on the CPU port).

2. Some DSA drivers always configure the CPU port as egress-tagged, in
an attempt to recover the classified VLAN from the skb. These drivers
cannot work at all with untagged traffic when bridged in
vlan_filtering=0 mode. And they can't go for the easy "just keep the
pvid as egress-untagged towards the CPU" route, because each front port
can have its own pvid, and that might require conflicting VLAN
membership settings on the CPU port (swp1 is pvid for VID 1 and
egress-tagged for VID 2; swp2 is egress-taggeed for VID 1 and pvid for
VID 2; with this simplistic approach, the CPU port, which is really a
separate hardware entity and has its own VLAN membership settings, would
end up being egress-untagged in both VID 1 and VID 2, therefore losing
the VLAN tags of ingress traffic).

So the only thing we can do is to create a helper function for resolving
the problematic case (that is, a function which untags the bridge pvid
when that is in vlan_filtering=0 mode), which taggers in need should
call. It isn't called from the generic DSA receive path because there
are drivers that fall neither in the first nor second category.

Introduce mbox tracepoints for Octeontx2

This patchset adds tracepoints support for mailbox.
In Octeontx2, PFs and VFs need to communicate with AF
for allocating and freeing resources. Once all the
configuration is done by AF for a PF/VF then packet I/O
can happen on PF/VF queues. When an interface
is brought up many mailbox messages are sent
to AF for initializing queues. Say a VF is brought up
then each message is sent to PF and PF forwards to
AF and response also traverses from AF to PF and then VF.
To aid debugging, tracepoints are added at places where
messages are allocated, sent and message interrupts.
Below is the trace of one of the messages from VF to AF
and AF response back to VF:
