- Why I did it
Sonic devices advertise themeselves as simple "debian" over lldp instead of sonic
- How I did it

Introduce a template that reads sonic software build version and Hardware information from config_db.json. This information is set in the system description.
- How to verify it
show lldp neighbors Ethernet16
- Which release branch to backport (provide reason below if selected)

201811
201911
202006

- Description for the changelog

- A picture of a cute animal (not mandatory but encouraged)

can this be added to lldpd.conf.j2 instead of creating another template file ?

do you want the lldod.conf an lldpdSysDescr.conf to be int a single file? if not, you could rewrite as:

We need to touch /etc/sonic/minigraph.xml. But since it is an automation run, we cannot do that manually. VS full build has happened successfully.

that is not the error. error is here.

processes_status': {'lldp': {'status': False, 'exited_critical_process': [u'lldp-syncd', u'lldpmgrd']

please check why lldp-syncd or lldpmgrd exited. looks like something in the pr breaks the image.

@abdosi , @lguohan , @tahmed-dev ,
I have looked at the logs, but there are no traces indicating why it has crashed. Can anyone tell me the reason for the crash ?

there are dump logs from the run, please take a look.

The error shown is fixed in https://github.com/Azure/sonic-buildimage/pull/6118/files. Thus this pull request is dependent on #6118 . Hence #6114 should go after #6118 .
