Adding platform support for FS s5800-48t4s and s5800-48t8s-mars8p.
Both s5800-48t4s and s5800-48t8s-mars8p have 48 * 10/100/1000 Base-T ports, 4 * 10GE SFP+ Ports on Centec TsingMa.
s5800-48t4s is different from s5800-48t8s-mars8p in that:
The phy chip used by s5800-48t4s is Marvell 88e1680;
The phy chip used by s5800-48t4s-mars8p is Centec ctc21108;
Why I did it
This is to fix test_forward_ip_packet_with_0xffff_chksum_tolerant test failure on 720DT-48S. IP packets with checksum set to 0xffff will be forwarded with the same checksum on this platform, instead of updating to the correct value.
How I did it
Add bcm config sai_verify_incoming_chksum=0 so that checksum is updated instead of being left unchanged when checksum is 0xffff. Note that packets with invalid checksum are still dropped with this config.
Why I did it
On DNX (J2/J2c/J2c+) platforms, Single Path Nexthops and ECMp Nexthop resources(FECs) are shared. BRCM SAI do not have partition of this resource, and hence more single path Nexthop entries, causes ECMP programming to fail in scaled setup.
How I did it
Broadcom provided SAI changes to reserve resources for single path nexthop entries(More details in CSP: https://brcmsemiconductor-csm.wolkenservicedesk.com/wolken-support/allcases/request-details?requestId=CS00012251649).
Along with SAI changes, they provided configurable Macro/flag to reserve NON_ECMP entries.
This PR is to add that flag in various sai.profile files wherever applicable.
PS: We are reserving 3072 single path Nexthop entries on each Linecard. Calculation is as follows.
Max Slots per chassis: 8
Max No of Ports(each LC): 64
MyIP/Subnet Entries per port: 4(v4/v6)
Nbr Entries Per port: 2(v4/v6)
Total Non_ECMP Count: 8x64x(4+2) = 3072
How to verify it
Without this change, the ECMP group count will be shown as Max_count in 'crm show resources all' command, and with this change the ECMP group count will be decreased by 24(3072/128).
Port indexes of front panel ports are not contiguous in multi-asic because we didn't distiguish between
front panel and internal ports, e.g., recycle ports. Fix this by assigning index to front panel port first
and then internal ports.

#### Why I did it
1. `eval()` - not secure against maliciously constructed input, can be dangerous if used to evaluate dynamic content. This may be a code injection vulnerability.
2. `subprocess()` - when using with `shell=True` is dangerous. Using subprocess function without a static string can lead to command injection.
3. `os` - not secure against maliciously constructed input and dangerous if used to evaluate dynamic content.
4. `is` operator - string comparison should not be used with reference equality.
5. `globals()` - extremely dangerous because it may allow an attacker to execute arbitrary code on the system
#### How I did it
1. `eval()` - use `literal_eval()`
2. `subprocess()` - use `shell=False` instead. use an array string. Ref: [https://semgrep.dev/docs/cheat-sheets/python-command-injection/#mitigation](https://semgrep.dev/docs/cheat-sheets/python-command-injection/#mitigation)
3. `os` - use with `subprocess`
4. `is` - replace by `==` operator for value equality
5. `globals()` - avoid the use of globals()
This change is to disable the pcie firmware check done by Broadcom SAI. The change is needed for the Arista platform x86_64-arista_7050cx3_32s; otherwise, the check will fail, blocking the initialization.
There was a pcie firmware check added in brcm SDK and certain Arista hardwares do not compliant with the check, so we added the disable_pcie_firmware_check originally for x86_64-arista_7060dx4_32. For x86_64-arista_7050cx3_32s, it was able to pass the check but some firmware change done in August made it fail.

Multi-asic Docker instances are created behind Docker's default bridge

After PFC interop testing between 8102 and 7050cx3, data packet losses were observed on the Rx ports of the 7050cx3 (inflow from 8102) during testing. This was primarily due to the slower response times to react to PFC pause packets for the 8102, when receiving such frames from neighboring devices. To solve for the packet drops, the 7050cx3 pg headroom size has to be increased to 160kB.
How I did it
Modified the xoff threshold value to 160kB in the pg_profile file to allow for the buffer manager to read that value when building the image, and configuring the device

Support Mellanox-SN4600C-C64 as T1 switch in dual-ToR scenario
This is to port #11032 and #11299 from 202012 to master.
Support additional queue and PG in buffer templates, including both traditional and dynamic model
Support mapping DSCP 2/6 to lossless traffic in the QoS template.
Add macros to generate additional lossless PG in the dynamic model
Adjust the order in which the generic/dedicated (with additional lossless queues) macros are checked and called to generate buffer tables in common template buffers_config.j2
Buffer tables are rendered via using macros.
Both generic and dedicated macros are defined on our platform. Currently, the generic one is called as long as it is defined, which causes the generic one always being called on our platform. To avoid it, the dedicated macrio is checked and called first and then the generic ones.
Support MAP_PFC_PRIORITY_TO_PRIORITY_GROUP on ports with additional lossless queues.
On Mellanox-SN4600C-C64, buffer configuration for t1 is calculated as:
40 * 100G downlink ports with 4 lossless PGs/queues, 1 lossy PG, and 3 lossy queues
16 * 100G uplink ports with 2 lossless PGs/queues, 1 lossy PG, and 5 lossy queues

* Why I did it
Followup to #10656. This change adds the remaining configs for the 720DT-48S platform.
* How I did it
Adds the following:
gearbox_config.json and other gearbox-related config files, to enable traffic on external PHY ports (Ethernet0-23)
sensors.conf
pcie.yaml
Also add missing facts in platform.json
* How to verify it
show interfaces status shows links up on interfaces Ethernet0-23
traffic flows with no errors on interfaces Ethernet0-23
Note: above testing depends on Add gbsyncd container for broncos #11154 and [orchagent]: Enhance initSaiPhyApi sonic-swss#2367, as well as having the appropriate PAI driver.

Why I did it
Improve throughput and latency for 7260 deployments
How I did it
Update the dynamic threshold to 0 and ECN settings as 2mb/10mb/5%
How to verify it
Updated unit tests to use the modified values for 7260 ecn settings.
Why I did it
This was an ask by Microsoft to provide:
7260 config.bcm file for hardware sku Arista-7260CX3-D92C16 (Named Arista-7260CX3-D96C16).
There are 16 100G uplinks:
Ethernet13-20/1
Ethernet45-52/1
All other ports are breakout to 2 50G ports.
How I did it
Copied existing Arista-7260CX3-D108C8 HWSKU and altered the bcm.config and port_config.ini files.
How to verify it
The new 100G ports do come up with a 201811 image using this HWSKU.
