selftests: forwarding: Add VRF-based tests
One of the nice things about network namespaces is that they allow one
to easily create and test complex environments.
Unfortunately, these namespaces can not be used with actual switching
ASICs, as their ports can not be migrated to other network namespaces
(NETIF_F_NETNS_LOCAL) and most of them probably do not support the
L1-separation provided by namespaces.
However, a similar kind of flexibility can be achieved by using VRFs and
by looping the switch ports together. For example:
br0
+
vrf-h1 | vrf-h2
+ +---+----+ +
| | | |
192.0.2.1/24 + + + + 192.0.2.2/24
swp1 swp2 swp3 swp4
+ + + +
| | | |
+--------+ +--------+
The VRFs act as lightweight namespaces representing hosts connected to
the switch.
This approach for testing switch ASICs has several advantages over the
traditional method that requires multiple physical machines, to name a
few:
1. Only the device under test (DUT) is being tested without noise from
other system.
2. Ability to easily provision complex topologies. Testing bridging
between 4-ports LAGs or 8-way ECMP requires many physical links that are
not always available. With the VRF-based approach one merely needs to
loopback more ports.
These tests are written with switch ASICs in mind, but they can be run
on any Linux box using veth pairs to emulate physical loopbacks.
v2:
* Order local variables declaration according to function arguments
order (Petr)
v1:
* Change location to net/forwarding instead of forwarding/
* Add ability to pause on failure
* Add ability to pause on cleanup
* Make configuration file optional
* Make ping/ping6/mz configurable
* Add more tc tests

This changeset moves ipvlan address under RCU protection, using
a per ipvlan device spinlock to protect list mutation and RCU
read access to protect list traversal.
Also explicitly use RCU read lock to traverse the per port
ipvlans list, so that we can now perform a full address lookup
without asserting the RTNL lock.
Overall this allows the ipvlan driver to check fully for duplicate

mlxsw: Offload multi-queue RED support
Nogah says:

+-------+ +--------+ +--------+
When setting sch_prio as the root qdisc on a physical port, mlxsw will
offload it. When adding it with sch_red as a child qdisc, it will offload
it as well.
Relocating child qdisc or connecting them to more then one child will
result in unoffloading them. Relocating child qdisc more then once is
highly unrecommended and might cause a miss match between the kernel
configuration and the offloaded one. The offloaded configuration will be
aligned with the one shown in the show command.
Changing the priomap parameter of sch_prio might cause a band that its
configuration was changed and it has offloaded sch_red set on it, to lose
some stats data as if sch_red was unoffloaded and offloaded again. However,
it won't affect the data on this band that will have sch_red continuously.
Patch 1 adds support for setting RED as the child of root qdisc.
Patches 2-4 add support for RED bstasts for offloaded child qdiscs.
Patches 5-6 handle backlog related changes for offloaded child qdiscs.
Patches 7-8 update PRIO in mlxsw to be able to have RED as child on its
bands.

Marvell PPv2 controller allows for generic packet filtering. This commit
adds entries to implement VLAN filtering. The approach taken is :
- Filter entries that would match on the presence of the VLAN tag
(existing VLAN detection, DSA / EDSA detection) will set the next
lookup ID to be for the VID.
- For each VLAN existing on a given port, we add an entry that matches
this specific VID. If the incoming packet matches the VID entry, it is
set for the next lookup in the chain (LU_L2).
- A Guard entry is added for each port, that will match if the incoming
packet didn't match any of the above VID entries. This entry tags the
packet to be dropped.
Due to this design, and the fact that the total 256 filter entries are
also used for other purposes, we have a limit of 10 VLANs per port. To
accommodate the case where we would need more VLANS on one port, this
patch implements the ndo_set_features to allow for disabling of VLAN
filtering using ethtool.
The default config has VLAN filtering disabled.
