Why I did it
According to ACL-Table-Type-HLD, the value type of MATCHES, ACTIONS and BIND_POINTS should be list instead of string. Opening this PR to update the definition of BMCDATA and BMCDATAV6.
How I did it
Update the definition of BMCDATA and BMCDATAV6 in minigraph-parser.
How to verify it
Verified by UT and build SONiC image.
Added support data for fabric monitoring in CONFIG_DB
The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}
The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}

How to verify it
Ran unittest to verify this update:
* Re-add 127.0.0.1/8 when bringing down the interfaces
With #5353, 127.0.0.1/16 was added to the lo interface, and then
127.0.0.1/8 was removed. However, when bringing down the lo interface,
like during a config reload, 127.0.0.1/16 gets removed, but 127.0.0.1/8
isn't added back to the interface. This means that there's a period of
time where 127.0.0.1 is not available at all, and services that need to
connect to 127.0.01 (such as for redis DB) will fail.
To fix this, when going down, add 127.0.0.1/8. Add this address before
the existing configuration gets removed, so that 127.0.0.1 is available
at all times.
Note that running `ifdown lo` doesn't actually bring down the loopback
interface; the interface always stays "physically" up.

On SONiC T1 cisco 8101 HwSku, the speed changes are done from 400G to 100G needs to be supported on 400G ports.
To enable this, along with speed change the port lanes need to be changed. This PR has the changes to update the port lanes when such speed change happens.
Basically if Banwidth in minigraph.xml intends to enable a 100G speed on a 400G port, then the appropriate lane change and speed change needs to be invoked in mingraph parser
Example if port_config.ini dicatates the speed to be 400G and minigraph has 100G speed, then this changeneeds to be accommodated
# name lanes alias index speed channel
Ethernet96 1536,1537,1538,1539,1540,1541,1542,1543 etp12 12 400000 0
<DeviceLinkBase>
<ElementType>DeviceInterfaceLink</ElementType>
<EndDevice>ARISTA01T2</EndDevice>
<EndPort>Ethernet1</EndPort>
<StartDevice>Device-8101-01</StartDevice>
<StartPort>etp12</StartPort>
<Bandwidth>100000</Bandwidth>
</DeviceLinkBase>
These platforms today have 400g port with 8 serdes lines, and 100g will operate with 4 serdes lane. When the port speed changes from 400G to 100G the first 4 lanes will be used for 100G port.

Why I did it
For better accounting purposes, updating the ingress lossy traffic profile to use static threshold. This change is only intended for Th devices using RDMA-CENTRIC profiles
How I did it
Update the buffer templates for Th devices in RDMA-CENTRIC folder to use the correct threshold
How to verify it
Verified the changes manually on a Th device.
Existing unit tests render Th template from the RDMA-CENTRIC folder. Updated the expected output to use the correct threshold
Why I did it
SONiC currently does not identify 'EdgeZoneAggregator' neighbor. As a result, the buffer profile attached to those interfaces uses the default cable length which could cause ingress packet drops due to insufficient headroom. Hence, there is a need to update the buffer templates to identify such neighbors and assign the same cable length as used by the T1.
How I did it
Modified the buffer template to identify EdgeZoneAggregator as a neighbor device type and assign it the same cable length as a T1/leaf router.
How to verify it
Unit tests pass, and manually checked on a 7260 to see the changes take effect.

Why I did it
After the renaming of the asic_port_name in port_config.ini file (PR: #13053 ), the asic_ifname in port_config.ini is changed from '-ASIC<asic_id>' to just port. Example: 'Eth0-ASIC0' to 'Eth0'.
However, with this change a config_db generated via config load_minigraph would cause the EVERFLOW and EVERFLOWV6 tables under ACL_TABLE to not have any of non-LAG front panel interfaces. This was causing the EVERFLOW suite to fail.
How I did it
In parse_asic_external_neigbhors in minigraph.py there was a check that the asic_name.lower() (like asic0) is present in the port_alias_asic_map. However with -ASIC removed from the asic_ifname, the port_alias_asic_map would not have the asic_name and thus any non-LAG neighbor would not be included.
Fix was the ignore the asic name change as the port_alias_asic_map is already only looking for ports in just the same asic as asic_name.
How to verify it
Execute "config load_minigraph" with the mingraph which is generated by sonic-mgmt gen-minigraph script. And confirm ono-lag interface are present in the Everfloe table in the config_dbs.

#### Why I did it
When loading from minigraph, for port channels, don't create the members@ array in config_db in the PORTCHANNEL table. This is no longer needed or used.
In addition, when adding a port channel member from the CLI, that member doesn't get added into the members@ array, resulting in a bit of inconsistency. This gets rid of that inconsistency.

- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:

This PR is an enhancement of PR #13105
Because the input string of AttachTo for ACL table can appear in both port name group and port alias group, I added a logic to determine whether the string should be port name or port alias
If all the input strings belong to port name group, then we treat all of them as port name
If all the input strings belong to port alias, then we treat all of them as port alias
If all the input string belongs to both port alias group and port name group, we prefer port alias. The behavior is as before.
How I did it
Walk through all port names/alias in the input to make a decision.
How to verify it
Verified by adding UT.
Why I did it
This PR is to update minigraph.py to support both port alias and port name as input of AttachTo attribute of ACL table.
Before this change, only port alias is supported.
