2022-07-28 854d54e: Add support of mdio IPC server class using sai switch api and unix socket (sonic-net/sonic-sairedis#1080) (Jiahua Wang)
2022-07-27 513cb2a: [FlexCounter] Refactor FlexCounter class (sonic-net/sonic-sairedis#1073) (Junchao-Mellanox)

#### Why I did it

Structured events code like eventd, rsyslogplugin, requires changes made in swss-common

Submodule adds these newest commits:

56b0f18 (HEAD, origin/master, origin/HEAD, master) Events: APIs to set/get global options (sonic-net#672)
5467c89 Add changes to yml file to improve pytest (sonic-net#674)

#### How I did it

Updated git submodule

#### How to verify it

Check new commit pointer

)

Why I did it
Content of platform.json was outdated and some platform_tests/api of sonic-mgmt were failing.

How I did it
Added the necessary values to platform.json

How to verify it
Running platform_tests/api of sonic-mgmt should yield 100% passrate.

…onic-net#11857)

As part of PR sonic-net#11754

    Change was added to use variable SONIC_DB_NS_CLI for
    namespace but that will not work since ./files/scripts/syncd_common.sh
    uses SONIC_DB_CLI. So revert back to use SONIC_DB_CLI and define new
    variable for SONIC_GLOBAL_DB_CLI for global/host db cli access

   Also fixed DB_CLI not working for namespace.

#### Why I did it
Fix the build failure caused by the installer image size too small. The installer image is only used during the build, not impact the final images.
See https://dev.azure.com/mssonic/build/_build/results?buildId=139926&view=logs&j=cef3d8a9-152e-5193-620b-567dc18af272&t=359769c4-8b5e-5976-a793-85da132e0a6f

#### How I did it
Increase the size from 2048M to 4096M.
Why not increase to 16G like qcow2 image?
The qcow2 supports the sparse disk, although a big disk size allocated, but it will not consume the real disk size. The falocate does not support the sparse disk. We do not want to allocate a very big disk, but no use at all. It will require more space to build.

* Update sensor names for msn4600c for the 5.10 kernel

Looks like a sensor was removed in the 5.10 kernel for the tps53679
sensor, so the names/indexing has changed.

The current error handling code for when a deb package fails to be
installed currently has a chain of commands linked together by && and
ends with `exit 1`. The assumption is that the commands would succeed,
and the last `exit 1` would end it with a non-zero return code, thus
fully failing the target and causing the build to stop because of bash's
-e flag.

However, if one of the commands prior to `exit 1` returns a non-zero
return code, then bash won't actually treat it as a terminating error.
From bash's man page:

```
-e      Exit immediately if a pipeline (which may consist of a single simple
	command), a list, or a compound command (see SHELL GRAMMAR above),
        exits with a non-zero status.  The shell does not exit if the
        command that fails is part of the  command  list  immediately
        following a while or until keyword, part of the test following the
        if or elif reserved words, part of any command executed in a && or
        || list except the command following the final && or ||, any
        command in a pipeline but the last, or if the command's return
        value is being inverted with !.  If a compound command other than a
        subshell returns a non-zero status because a command failed while
        -e was being ignored, the shell does not exit.
```

The part `part of any command executed in a && or || list except the
command following the final && or ||` says that if the failing command
is not the `exit 1` that we have at the end, then bash doesn't treat it
as an error and exit immediately. Additionally, since this is a compound
command, but isn't in a subshell (subshell are marked by `(` and `)`,
whereas `{` and `}` just tells bash to run the commands in the current
environment), bash doesn't exist. The result of this is that in the
deb-install target, if a package installation fails, it may be
infinitely stuck in that while-loop.

There are two fixes for this: change to using a subshell, or use `;`
instead of `&&`. Using a subshell would, I think, require exporting any
shell variables used in the subshell, so I chose to change the `&&` to
`;`. In addition, at the start of the subshell, `set +e` is added in,
which removes the exit-on-error handling of bash. This makes sure that
all commands are run (the output of which may help for debugging) and
that it still exits with 1, which will then fully fail the target.

The check_install.py was waiting for the message "sonic login:", and Linux console was waiting for the username input (the login message has already printed in the console).

If entering a newline, the message "sonic login:" will prompt again.

sonic-net#11891)

Why I did it
Fix the official build not triggered correctly issue, caused by the azp template path not existing.

How I did it
Change the azp template path.

Why I did it
To gracefully unmount filesystems and stop containers while performing a cold reboot.
Unmount ONIE-BOOT if mounted during fast/soft/warm reboot
How I did it
Override systemd-reboot service to perform a cold reboot.
Unmount ONIE-BOOT if mounted using fast/soft/warm-reboot plugins.
How to verify it
On reboot, verify that the container stop and filesystem unmount services have completed execution before the platform reboot.

Why I did it:
API get_device_runtime_metadata() added by sonic-net#11795 uses merge operator for dict but that is supported only for python version >=3.9. This API will be be used by scrips eg:hostcfgd which is still build for buster which does not have python 3.9 support.

…esting with cisco 8102 (sonic-net#11901)

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

How to verify it
run "mmuconfig -l" once image is built
