Created a GitHub PR against 5.4.78 with the core functions listed above, ixbe and QAT in-tree as well as wireguard (avoids the convoluted module builds and permits LTO/CFI passes)

@c-po This task has been completed for so long, can the PR be reviewed?
PR: https://github.com/vyos/vyos-1x/pull/508

I took a brief look, the ip command seems to support the relevant tunnel type

TYPE := { vlan | veth | vcan | vxcan | dummy | ifb | macvlan | macvtap |
           bridge | bond | team | ipoib | ip6tnl | ipip | sit | vxlan |
           gre | gretap | erspan | ip6gre | ip6gretap | ip6erspan |
           vti | nlmon | team_slave | bond_slave | bridge_slave |
           ipvlan | ipvtap | geneve | vrf | macsec | netdevsim | rmnet |
           xfrm }

Another bug that the following configuration doesn't configure vtysh level debug

Perfect. Thanks.

The main reason is frr code for placing log files in a separate file.
https://github.com/FRRouting/frr/blob/master/tools/etc/rsyslog.d/45-frr.conf

That is the idea.

So if one uses

set system ntp server <server>

it will render on ntp.conf

server <server> iburst

1. Totally agree with this. We had this same issue when we used to run Vyatta. Took me ages to figure out too.

However, I'm not sure what would be the best way to implement this is? I read a good explanation here about when to increase and change interrupt settings.
Do you think a config option is best e.g.
set interfaces ethernet eth0 advanced ring rx nnnn

Why not introduce a new pool option like: set system ntp server <server> pool ?

Its not a bug of VyOS. The net-snmp linux package we utilize does not support more OIDs.

Vtun interfaces are now created prior to starting OpenVPN to always ensure there is a kernel interface available
