c11ed48733 Ignore link-local routes in SBR tests
The tests were flaky due to a route with the link-local IP being
automatically added after the test run saves the initial state
(routes before SBR plugin is ran). When the SBR plugin is ran,
the new state is compared with the old state. The new state will
then contain the route with the link-local IP (that has been
added after saving the old state), the old state was not
containing it, so the tests were failing

The solution here is to ignore routes with the link-local IP
for the tests.

cc8b1bd80c dhcp: Add priority option to dhcp.
Currently, we can not set the metric of routes in dhcp.
It's ok if there is only a network interface.

But if there are multiple network interfaces, and both have a default route,
We need to set the metric of the route to make the traffic
go through the correct network interface.

For host-local and static, we can set the metric with the route.priority option.
But there is no such option for dhcp.

SBR: option to pass the table id (#1088)
* Use of Table ID in IPAM

Signed-off-by: Lionel Jouin <lionel.jouin@est.tech>

* SBR: option to pass the table id

Using the option to set the table number in the SBR meta plugin will
create a policy route for each IP added for the interface returned by
the main plugin.
Unlike the default behavior, the routes will not be moved to the table.
The default behavior of the SBR plugin is kept if the table id is not set.

52da39d3aa bandwidth: possibility to exclude some subnets from traffic shaping
what changed:

we had to refactor the bandwidth plugin and switch from a classless qdisc (tbf)
to a classful qdisc (htb).

subnets are to be provided in config or runtimeconfig just like other parameters

unit and integration tests were also adapted in consequence

unrelated changes:

test fixes: the most important tests were just silently skipped due to ginkgo Measure deprecation
(the ones actually checking the effectiveness of the traffic control)

Use temporary name for netdevice when moving in/out of NS
Today, it is not possible to use host-device CNI to move a
host device to container namespace if a device already exists
in that namespace.

e.g when a delegate plugin (such as multus) is used to provide
multiple networks to a container, CNI Add call will fail if
the targeted host device name already exists in container network
namespace.

to overcome this, we use a temporary name for the interface before
moving it in/out of container network namespace.

Support DeviceID on Auxiliary Bus
Device plugins may allocate network device on a bus
different than PCI.

sriov-network-device-plugin supports the allocation
of network devices over Auxiliary bus[1][2][3].

extend host-device CNI to support such devices if provided
through runtime config.

- Check if device provided by DeviceID runtime config
  is present on either PCI bus or Auxiliary bus
- extend getLink method to support getting netdev link obj
  from auxiliary bus
- add unit-test to cover the new flow

7e131a0076 bridge: Enable disabling bridge interface
The new `disableContainerInterface` parameter is added to the bridge plugin to
enable setting the container interface state down.

When the parameter is enabled, the container interface (veth peer that is placed
at the container ns) remain down (i.e: disabled).
The bridge and host peer interfaces state are not affected by the parameter.

Since IPAM logic involve various configurations including waiting for addresses
to be realized and setting the interface state UP, the new parameter cannot work
with IPAM.
In case both IPAM and DisableContainerInterface parameters are set, the bridge
plugin will raise an error.

48aa2f4eef Fix race conditions in DHCP test
The test named "correctly handles multiple DELs for the same container" in the ipam/dhcp package experiences race conditions when multiple goroutines concurrently access and modify the Args struct (of type CmdArgs).
To address these issues, a copy of the CmdArgs struct is now created in each function to eliminate data races.

Also, the test-linux.sh and test-windows.sh scripts have been updated to include the '-race' flag, enabling race detection during testing. This change helps prevent future race conditions by activating the Go race detector.
