changed the platform device name under nokia directory; we now need to specify marvell armhf/arm64 to provide more accurate platform identity. otherwise onie discovery won't recognize the asic being installed.

Multi-asic Docker instances are created behind Docker's default bridge
which doesn't allow talking to other Docker instances that are in the
host network (like database-chassis).
On linecards, we configure midplane interfaces to let per-asic docker
containers talk to CHASSIS_DB on the supervisor through internal chassis
network.
On the supervisor we don't need to use chassis internal network, but we
still need a similar setup in order to allow fabric containers to talk
to database-chassis

Why I did it
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

Add lossy PG profile for PG2 and PG6 on T1 for ports between T1 and T2.
After PR Update qos config to clear queues for bounced back traffic #10176 , the DSCP_TO_TC_MAP and TC_TO_PG_MAP is updated when remapping is enable
DSCP_TO_TC_MAP
Before After Why do this change
"2" : "1" "2" : "2" Only change for leaf router to map DSCP 2 to TC 2 as TC 2 will be used for lossless TC
"6" : "1" "6" : "6" Only change for leaf router to map DSCP 6 to TC 6 as TC 6 will be used for lossless TC
TC_TO_PRIORITY_GROUP_MAP
Before After Why do this change
"2" : "0" "2" : "2" Only change for leaf router to map TC 2 to PG 2 as PG 2 will be used for lossless PG
"6" : "0" "6" : "6" Only change for leaf router to map TC 6 to PG 6 as PG 6 will be used for lossless PG
So, we have two new lossy PGs (2 and 6) for the T2 facing ports on T1, and two new lossless PGs (2 and 6) for the T0 facing port on T1.
However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.
How I did it
Update the qos and buffer template.
How to verify it
Verified by UT.
Why I did it
As part of PCBB changes, we need to enable 2 extra lossless queues. The changes in this PR are done to adjust only the reserved sizes on Th2 for the additional 2 lossless queues
Calculations are done based on 40 downlinks for T1 and 16 uplinks for dual ToR
How to verify it
Verified that the rendering works fine on Th2 dut

What/Why I did:
Issue1: By setting up of ipvlan interface in interface-config.sh we are not tolerant to failures. Reason being interface-config.service is one-shot and do not have restart capability.
Scenario: For example if let's say database service goes in fail state then interface-services also gets failed because of dependency check but later database service gets restart but interface service will remain in stuck state and the ipvlan interface nevers get created.
Solution: Moved all the logic in database service from interface-config service which looks more align logically also since the namespace is created here and all the network setting (sysctl) are happening here.With this if database starts we recreate the interface.
Issue 2: Use of IPVLAN vs MACVLAN
Currently we are using ipvlan mode. However above failure scenario is not handle correctly by ipvlan mode. Once the ipvlan interface is created and ip address assign to it and if we restart interface-config or database (new PR) service Linux Kernel gives error "Error: Address already assigned to an ipvlan device." based on this:https://github.com/torvalds/linux/blob/master/drivers/net/ipvlan/ipvlan_main.c#L978Reason being if we do not do cleanup of ip address assignment (need to be unique for IPVLAN) it remains in Kernel Database and never goes to free pool even though namespace is deleted.
Solution: Considering this hard dependency of unique ip macvlan mode is better for us and since everything is managed by Linux Kernel and no dependency for on user configured IP address.
Issue3: Namespace database Service do not check reachability to Supervisor Redis Chassis Server.
Currently there is no explicit check as we never do Redis PING from namespace to Supervisor Redis Chassis Server. With this check it's possible we will start database and all other docker even though there is no connectivity and will hit the error/failure late in cycle
Solution: Added explicit PING from namespace that will check this reachability.
Issue 4:flushdb give exception when trying to accces Chassis Server DB over Unix Sokcet.
Solution: Handle gracefully via try..except and log the message.
