Currently the simult_flows.sh self-tests are not very stable,
especially when running on slow VMs.

The tests measure runtime for transfers on multiple subflows
and check that the time is near the theoretical maximum.

The current test infra introduces a bit of jitter in test
runtime, due to multiple explicit delays. Additionally the
runtime is measured by the shell script wrapper. On a slow
VM, the script overhead is measurable and subject to relevant
jitter.

One solution to make the test more stable would be adding more
slack to the expected time; that could possibly hide real
regressions. Instead move the measurement inside the command
doing the transfer, and drop most unneeded sleeps.

Ariel Levkovich says:

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

Support HW offload of TC rules involving OVS internal port
device type as the filter device or the destination
device.

The support is for flows which explicitly use the internal
port as source or destination device as well as indirect offload
for flows performing tunnel set or unset via a tunnel device
and the internal port is the tunnel overlay device.

Since flows with internal port as source port are added
as egress rules while redirecting to internal port is done
as an ingress redirect, the series introduces the necessary
changes in mlx5_core driver to support the new types of flows
and actions.

br_switchdev_mdb_notify() is conditionally compiled only when
CONFIG_NET_SWITCHDEV=y and CONFIG_BRIDGE_IGMP_SNOOPING=y. It is called
from br_mdb.c, which is conditionally compiled only when
CONFIG_BRIDGE_IGMP_SNOOPING=y.

The shim definition of br_switchdev_mdb_notify() is therefore needed for
the case where CONFIG_NET_SWITCHDEV=n, however we mistakenly put it
there for the case where CONFIG_BRIDGE_IGMP_SNOOPING=n. This results in
build failures when CONFIG_BRIDGE_IGMP_SNOOPING=y and
CONFIG_NET_SWITCHDEV=n.

To fix this, put the shim definition right next to

Since this is called only from br_mdb.c, we need not take any extra
safety precautions, when NET_SWITCHDEV=n and BRIDGE_IGMP_SNOOPING=n,
this shim definition will be absent but nobody will be needing it.

This is because it is not known from where the packet

a term table is required to perform hairpin.
If the packet arrived from a vport, going via term

In case a rule is added to a tc block of an internal port,

Therefore, only packets that previously hit a rule that redirects

to after the encapsulation. This is the device that has the

This change adds support to offload an encap rule where the

In such case, the driver will add a HW rule that will encapsulate

value that is mapped for this internal port using the internal

After that the hw rule will redirect the packet to the root table

The new vport metadata value indicates that this packet is now
arriving through an internal port and therefore should be processed
using rules that apply on the same internal port as the filter device.
Therefore, following rules that apply on this internal port will have
to match on the same vport metadata value as part of their matching

Setting the skb packet type field to host is usually
done when performing forwarding to ingress device.

This is required since the receive handling that is used
by the redirect to ingress action checks whether the packet
doesn't belong to this host and drops the packet in such case.

In order to be able to offload action redirect ingress, tc offload
code needs to accept the skbedit ptype action as well.

There's no special handling in HW for such action since it will
be followed by a redirect action and therefore, this code
only allows us to accept such action in the actions list but
not performing anything specific in HW for it.

Adding infrastructure to map ovs internal port device to vport
match metadata to support offload of rules with internal port as
the filter device or as the destination device.

The infrastructure allows adding and removing internal port device
to an eswitch database and getting a unique vport metadata value to
be placed and match on in reg_c0 when offloading rules that are coming
from or going to an internal port.

The new int port metadata can be written to the source port register
in HW to indicate that current source port of the packet is the
internal port and not one of the actual HW vports (uplink or VF).
Using this method, it is possible to offload TC rules with an OVS
internal port as their destination port (overwriting the src vport
register) or as the filter port (matching on the value of the src
vport register and making sure it matches to the internal port's
value).

There is also a need to handle a miss case where the packet's
src port value was changed in HW to an internal port but a following
rule which matches on this new src port value wasn't found in HW.

In such case, the packet will be forwarded to the driver with
metadata which allows driver to restore the info of the internal
port's netdevice. Once this info is restored, the uplink driver
can forward the packet to the relevant netdevice in SW.

Fix driver not freeing VF's traffic irqs, prior to calling
pci_disable_msix in iavf_remove.
There were possible 2 erroneous states in which, iavf_close would
not be called.
One erroneous state is fixed by allowing netdev to register, when state
is already running. It was possible for VF adapter to enter state loop
from running to resetting, where iavf_open would subsequently fail.
If user would then unload driver/remove VF pci, iavf_close would not be
called, as the netdev was not registered, leaving traffic pcis still
allocated.
Fixed this by breaking loop, allowing netdev to open device when adapter
state is __IAVF_RUNNING and it is not explicitily downed.
Other possiblity is entering to iavf_remove from __IAVF_RESETTING state,
where iavf_close would not free irqs, but just return 0.
Fixed this by checking for last adapter state and then removing irqs.

Add helper function to go from pci_dev to adapter to make work simple -
to go from a pci_dev to the adapter structure and make netdev assignment
instead of having to go to the net_device then the adapter.

Currently raw hex values are used to define specific bits for each
capability/offload in virtchnl.h. Using raw hex values makes it
unclear which bits are used/available. Fix this by using the BIT()
macro so it's immediately obvious which bits are used/available.

Also, move the VIRTCHNL_VF_CAP_ADV_LINK_SPEED define in the correct
place to line up with the other bit values and add a comment for its
purpose.

Remove unused define that is currently marked as reserved. This will
open up space for a new feature if/when it's introduced. Also, there is
no reason to keep unused defines around.

Disable showing bus-info information for port representors in switchdev
mode. This fixes a bug that caused displaying wrong netdev descriptions in
lshw tool - one port representor displayed PF branding string, and in turn
one PF displayed a "generic" description. The bug occurs when many devices
show the same bus-info in ethtool, which was the case in switchdev mode (PF
and its port representors displayed the same bus-info). The bug occurs only
if a port representor netdev appears before PF netdev in /proc/net/dev.

In the examples below:
ens6fX is PF
ens6fXvY is VF
ethX is port representor
One irrelevant column was removed from output

Before:
$ sudo lshw -c net -businfo
Bus info          Device      Description
=========================================
pci@0000:02:00.0  eth102       Ethernet Controller E810-XXV for SFP
pci@0000:02:00.1  ens6f1       Ethernet Controller E810-XXV for SFP
pci@0000:02:01.0  ens6f0v0     Ethernet Adaptive Virtual Function
pci@0000:02:01.1  ens6f0v1     Ethernet Adaptive Virtual Function
pci@0000:02:01.2  ens6f0v2     Ethernet Adaptive Virtual Function
pci@0000:02:00.0  ens6f0       Ethernet interface

Notice that eth102 and ens6f0 have the same bus-info and their descriptions
are swapped.

After:
$ sudo lshw -c net -businfo
Bus info          Device      Description
=========================================
pci@0000:02:00.0  ens6f0      Ethernet Controller E810-XXV for SFP

When spawning VFs in switchdev mode, internal filter list of VSIs is
cleared, which includes MAC rules. However MAC entries stay on netdev's
multicast list, which causes error message when bringing link up after
spawning VFs ("Failed to delete MAC filters"). __dev_mc_sync() is
called and tries to unsync addresses that were already removed
internally when adding VFs.

This can be reproduced with:
1) Load ice driver
2) Change PF to switchdev mode
3) Bring PF link up
4) Bring PF link down
5) Create a VF on PF
6) Bring PF link up

Added clearing of netdev's multicast (and also unicast) list when
spawning VFs in switchdev mode, so the state of internal rule list and
netdev's MAC list is consistent.

Currently, the vlan_promisc flag is used exclusively by VF VSI to
determine whether or not to toggle VLAN pruning along with
trusted/true-promiscuous mode. This is not needed for a couple of
reasons. First, trusted/true-promiscuous mode is only supposed to allow
all MAC filters within VLANs that a VF has added filters for, so VLAN
pruning should not be disabled. Second, the boolean argument makes the
function confusing and unintuitive. Remove this flag.
