What I did:-
Enhanced minigraph parser to parse interface name associated with static route nexthop
Why I did:-
One of the use case to support interface name is Chassis Packet. For Chassis Packet we have Static Routes configured to route traffic across line-card. If the FRR programs static route without the interface name then in case if the ip interface that is associated with the nexthop goes down FRR resolves static route nexthop over the default route as we have FRR config ip nht-resolve-via-default which causes undesired behavior. Having interface name with Static Route prevents recursive lookup on default route.

Closes#7958
#### Why I did it
The previous implementation of sonic-cfggen did a simple comparison between default breakout mode in
hwsku.json and supported modes in platform.json. To set a different default speed in hwsku.json
it was required to add one more entry to supported modes in platfrom.json file:
1x10G[100G,50G] vs 1x100G[50G,10G]
The new implementation does more intelligent parsing and analysis of supported and default modes. It
allows changing default speed without adding a new entry to platform.json.
#### How I did it
Add more intelligent parsing and analysis of supported and default modes.
#### How to verify it
Run sonic-config-engine unit tests from sonic-config-engine/tests directory
What I did:
Updated Jinja Template to enable BGP Graceful Restart based on device role. By default it will be enable only if the device role type is TorRouter.
Why I did:-
By default FRR is configured in Graceful Helper mode. Graceful Restart is needed on T0/TorRouter only since the device can go for warm-reboot. For T1/LeafRouter it need to be in Helper mode only

Updated BGP Template for the case:
1. For Packet Chassis do not advertise Loopback4096 address into BGP as there is Static Route for same.
Having this route in BGP causes two level of recursion in Zebra and cause assert in Zebra
when there are many nexthop involved
2. Advertise only P2P Connected IP's into BGP (External Peers). For Packet chassis we have backend IP Interface subnet and if
they get advertised into BGP then it also causes recursion

Why I did it
Support zero buffer profiles
Add buffer profiles and pool definition for zero buffer profiles
Support applying zero profiles on INACTIVE PORTS
Enable dynamic buffer manager to load zero pools and profiles from a JSON file
Dependency: It depends on Azure/sonic-swss#1910 and submodule advancing PR once the former merged.
How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
Apply normal buffer profiles to admin-up ports
Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
Apply normal buffer profiles to all ports
buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
Adjust example output file of JSON template for unit test
Add unit test in for Mellanox's new buffer templates.
How to verify it
Regression test.
Unit test in sonic-cfggen
Run regression test and manually test.

Why I did it
Storage T0's have all vlan members as tagged
How I did it
Since currently minigraph does not have a unique way to identify if a vlan member is tagged/untagged and to ensure other scenarios are not broken, the logic used is to just update the vlan member type as 'tagged' when we determine that it is a storage backend device. This change will apply only to storage backend T0's since storage backend T1's will not have vlan member information
How to verify it
Updated the storage backend T0 testcases to check for tagged vlan members
Added testcase to check if a T1 and backend T1 device generates an empty vlan member table
Existing vlan member testcases are good enough for checking if any regression has been caused for regular T0's
Build sonic_config_engine-1.0-py3-none-any.whl successfully
Fix the check used to wait for interfaces to come up. The group name in
the supervisor config files has changed from isc-dhcp-relay to
dhcp-relay.
Also, in the wait script, wait 10 additional seconds after the vlans,
port channels, and any interfaces are up. This is because dhcrelay
listens on all interfaces (in addition to port channels and vlans), and
to ensure that it stays in a clean state during runtime, wait some extra
time to make sure that those interfaces are created as well.

QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:

"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"

"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.

To Fix#8697 . The config load_minigraph initializes 'admin_status' to up when platform.json has DPB configs. This doesn't happen when using port_config.ini
The update minigraph has logic to initialize only the ports whose neighbors are defined or those belonging to portchannel
However, a change was introduced to have default admin status to be 'up' in portconfig.py when the minigraph was using platform.json
This will lead to sanity check failure in sonic-mgmt and thus no test cases could be run
#### Why I did it
Allow cfggen to work on system without ports in platform.json or in port_config.ini
#### How I did it
Add json write of PORT section only if the dictionary that contains the ports is not empty.

Fix for sonic-cfggen exception during platform string read during fresh install and start of sonic in multi asic, /var/run/redisX/ is created after database docker is started.
In version 3.0.0, If a broadcast address is specified in
/etc/network/interfaces, then when ifup is run, it will fail with an
error saying `'str' object has no attribute 'packed'`. This appears to
be because it expects all attributes for an interface to be "packable"
into a compact binary representation. However, it doesn't actually
convert the broadcast address into an IPNetwork object (other addresses
are handled).
Therefore, convert the broadcast address it reads in from a str to an
IPNetwork object.
Also explicitly specify the scope of the loopback address in
/etc/network/interfaces as host scope. Otherwise, it will get added as
global scope by default. As part of this, use JSON to parse ip's output
instead of text, for robustness.

Signed-off-by: Neetha John <nejo@microsoft.com>
As part of the buffer reclamation efforts for TD2, setting the default cable len to 0m which means unused ports will have a cable len of 0m.
Why I did it
To align with the changes in Azure/sonic-swss#1830
How to verify it
- With the default cable len set to 0m and the associated changes in swss, CABLE_LENGTH table had '0m' set for unused ports and accordingly more space was reserved for the shared pool
- Cfggen tests passed with the cable len update

Why I did it
There are scenarios that End-of-RIB comes from a part of the peers arrives after reconciliation. In such scenarios, if the route selection deferral timer has the default value of 360 seconds, FRR would not set up routes and all routes would be removed after reconciliation. This PR reduces the route selection deferral timer so that at least routes to parts of the peers get restored at the point of reconciliation.
Fix#7488
How I did it
Reduce route selection deferral timer for bgp graceful restart to 15 seconds.
lazy_re had an issue when importing sonic-cfggen in another application that
uses re.search(). There is no much improvement of lazy_re today after many
other good optimization work done for sonic-cfggen. It served as a quick
temporary solution.
Some quick test for fast-reboot and warm-reboot done on top of 201911 branch:
Fast-reboot: from ASIC reset to ports in up state:
with lazy_re: 18 sec
without lazy_re: 18 sec
Warm-reboot: LAG restoration time:
with lazy_re: 73 sec
without lazy_re: 72 sec
So, there is no real optimization since the number of sonic-cfggen calls is greatly
reduced in latest SONiC. This means it is time to revert this change.
