The CLI command 'set interfaces ethernet <interface> offload-options xdp" enables
the XDP generic mode on the given interface.

Description: fooa
XDP code is thankfully copied from [1], thank you for this nice tutorial.
NOTE: this is an experimental feature which might break your
forwarding/filtering.

This will render the completion help more nicely.

mpls-conf: T915: Add LDP import and export control
|
|
In this commit we added the ability to control import and export
of LDP FECs. This allows for an operator to specify which to
filter on ingress, and which to not announce on egress.

dhcp: T2562: add "listen-address" CLI node for better DHCP relay support
|
|
Running ISC DHCP server as backend server for multiple pools served to relay
agents requires DHCPd to explicitly listen on give interfaces or a "transit"
subnet declaration facing the network where we receive the DHCPREQ messages on.
This implements a new "listen-address" CLI node, the given address is validated
if it is assigned to the system and upon success, a proper "subnet { }" statement
is added into dhcpd.conf
|
|
In this commit we added the ability to control the local label allocation
control for FECs. It allows for the router to not allocate a label for every
interface, just the interfaces that are desired by the operator.

Commit 5f5b2808c0a ("ethernet: T3048: drop static smp-affinity for dynamic
performance tuning") but the CLI nodes have not been removed.

IPv6 enable can be considered once the ipv6 node is present!

Switch to common source file for "ipv6 address autoconf"

The NAT system consists out of nested tag nodes which makes manual parsing very
hard. This is a perfect candidate for migrating this to get_config_dict() as
there is already a smoketest in place.
In addition this should make it easier to add features like static nat/hairpin.

global features
So this is a big update.
The first thing that was done was a refactor to the FRR LDP template, MPLS handler, and XML conf tree MPLS global additions.
The refactors should work and I did test them in my lab. It seems that everything does work as needed so far in my testing.
There is something here that is considered configuration breaking from the old setup though. In the old setup the MPLS interface operation (as in the interfaces accepting MPLS labels and processing them) was tied with LDP. What this means is that MPLS processing was enabled at the same time as LDP interfaces were configured. We do not want this behavior for the future as there's other MPLS underlay technologies like SR and RSVP. If someone wants to enable SR or RSVP without enabling LDP then they now can. Before, they couldn't. The other additions are global changes to MPLS TTL propagation and MPLS max TTL enforcement. They have now been added.
Lastly, there is an frr-reload bug that Runar Borge found with this. We have found that when totally deleting LDP that there has to be 3 commits done. This is because frr-reload doesn't properly do what it needs to do in 1 operation so we had to do 3. This will only affect people that are doing an entire LDP clear using "delete protocols mpls ldp." Otherwise it isn't seen.
Anyway, this refactor now works with the FRR daemon directly for all changes. This also makes it much easier for adding stuff in the future.
Thank you

By design a CLI node should not be named by its plural but rather describe it
as singular.

link-local addresses can still be disabled using:
set interfaces wireguard wg0 ipv6 address no-default-link-local

This reverts commit 806f35b5856c3f8dae634718a6a9e82cc90bb63a.
Unfortunately this did not work our in the attempt to bridge a station to a
bridge "brX" interface. Also adjusting the wireless interface during operation
cause several exceptions and the feature is removed again as it was never in any
production system.

Python value
We should not use hardcoded Python values whenever possible. vyos.xml provides
an abstraction of the XML CLI definitions providing default values from the CLI
specified via the <defaultValue> node.
This increases consistency among all XML/Python wrappers.
Additional small fixes in this commit (besides the bad practice incorporating
unrelated changes into the same commit) contain:
- Keyboard layout shout be explicitly set for /dev/console
- Added missing Debian dependency on console-data
- When looking for a key in a dict, we do not need to specify dict.keys()

1. Due to the previous focus on the implementation of VLAN filter, it was not considered to include MTU settings, which will lead to MTU setting errors in some cases
2. In order to make VLAN aware of the work of the bridge, it is necessary to specify the allowed VLAN ID range for the bridge itself, and forget to join it before

This commit has to do with the addition of miscellaneous MPLS parameters, as well as miscellaneous LDP parameters. Per c-po, for miscellaneous options and whatnot that do not fit anywhere we will put them into a specific "parameters" node.
I also did some global linux configuration changes here. We make changes to kernel options "net.mpls.ip_ttl_propagate" and "net.mpls.default_ttl" which should allow the behavior of VyOS to have the same as routers from the big vendors.
I added two LDP options for cisco interoperation TLV and for a dual stack preference.
Lastly, I went through and changes some of the help/description fields in the definitions page because I just felt they weren't uniform and the words seemed to not properly explain what they were doing. I also did some code clean up (or tried to...) with comments and whatnot.

The commit has to do with the addition of targeted LDP neighbors and parameters being added. FRR allows for this functionality and I just wanted to add it.
We have basically 4 options that are added. Enabling targeted LDP functionality, the targeted neighbor, the hello interval of targeted sessions, and the hold time of targeted sessions. Both IPv4 and IPv6 has been coded in.

Some might want to have an IP address handed out by a DHCP server but not want
a default route to be installed. This can be done using the CLI command:
"set interfaces ethernet eth2 dhcp-options no-default-route"
