iproute2 package is fine with us, but there are some expectations:
syntax, command options and documentation need to be consistent with
other iproute2 commands (this thread suggests it will be but just being
clear), and it needs to re-use code as much as possible (e.g., json
functions). If there is overlap with other tools (devlink, dcb, etc),
you should refactor into common code used by all. Petr Machata has done
this quite a bit for dcb and is a good example to follow.

Sorry for my late reply. I missed your message until yesterday.
Thanks for the ack and inputs.
Yes, I migrated the iproute2/vdpa to use now uses the common code introduced by
dcb tool.
Waiting for kernel side to finish.
