Current lldp.conf.j2 template demands the presence of MGMT_INTERFACE attribute in configDB, and by extension, also in config_db.json file. However, MGMT_INTERFACE configuration attribute is optional, so lldp shouldn't bail out if this one isn't provided in configuration.
For this reason, no lldp.conf file is ever created in lldp's container, and lldpd defaults to advertise the mac-address of the connected interface, instead of the interface name.
The fix is to simply relax this jinja2 statement to verify if MGMT_INTERFACE attribute is present.
Just a simple change to make sonic's user life a little bit easier. Displaying the multiple elements of config_db.json in an orderly fashion allows a more intuitive user-experience.
For this change i'm simply intercepting the config-state that is about to be dumped to config_db.json, and i'm placing it in an ordered-dictionary, so that information is pushed to file in natural/alphanumerical ordering.
Example:
admin@lnos-x1-a-csw01:~$ sudo sonic-cfggen -m /etc/sonic/minigraph.xml --print-data
{
...
"PORT": {
"Ethernet0": {
"alias": "Eth1/1",

The current DEVICE_NEIGHBOR format doesn't support multiple different
ports connecting with same neighbor. Thus the lldpd.conf file is not
generated correctly, causing missing information for LAG members.
This fix reverts the data structure in the previous version of
minigraph parser - using local port as the key and remote port/device
as the value of the map. Sample format is:
DEVICE_NEIGHBOR['Ethernet124'] = {
'name': 'ARISTA04T1',
'port': 'Ethernet1/1'
}
The corresponding unit test in test_cfggen is updated.
Add one more unit test for lldpd.conf.j2 verification.

So here i'm just deleting this integrating-config file to prevent FRR from running from a bogus config-file.
