Why I did it
Some products might experience an occasional IO failure in the communication between CPU and SSD.
Based on some research it could be attributable to some device not handling ATA NCQ (Native Command Queue).
This issue currently affect 4 products:
DCS-7170-32C*
DCS-7170-64C
DCS-7060DX4-32
DCS-7260CX3-64
How I did it
This change disable NCQ on the affected drive for a small set of products.
How to verify it
When the fix is applied, these 2 patterns can be found in the dmesg.
ata1.00: FORCE: horkage modified (noncq)

The main issue is the pip/pip3 command cannot be found when the package is being installed by apt-get.
When using the dpkg install, the searching path is PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
When using the apt-get install, the searching path is PATH=/usr/sbin:/usr/bin:/sbin:/bin
But the pip/pip3 default path is at /usr/local/bin, so dpkg works, but apt-get not work.
How I did it
Export the path /usr/local/bin for pip/pip3.
Make the deb packages can be installed by apt-get.
Why I did it
The current lazy installer relies on a filename sort for both unpack and configuration steps. When systemd services are configured [started] by multiple packages the order is by filename not by the declared package dependencies. This can cause the start order of services to differ between first-boot and subsequent boots. Declared systemd service dependencies further exacerbate the issue (e.g. blocking the first-boot script).
The current installer leaves packages un-configured if the package dependency order does not match the filename order.
This also fixes a trivial bug in [Build]: Support to use symbol links for lazy installation targets to reduce the image size #10923 where externally downloaded dependencies are duplicated across lazy package device directories.
How I did it
Changed the staging and first-boot scripts to use apt-get:
dpkg -i /host/image-$SONIC_VERSION/platform/$platform/*.deb
becomes
apt-get -y install /host/image-$SONIC_VERSION/platform/$platform/*.deb
when dependencies are detected during image staging.
How to verify it
Apt-get critical rules
Add a Depends= to the control information of a package. Grep the syslog for rc.local between images and observe the configuration order of packages change.
Why I did it
nameserver and domain entries from build system fsroot gets into sonic image.
How I did it
Clear /etc/resolv.conf before building image
How to verify it
Built image with it and verified with install that /etc/resolv.conf is empty
* Fix to improve hostname handling
If config_db.json is missing hostname entry, hostname-config.sh ends
up deleting existing entry too and hostname changes to default 'localhost'
* default hostname to 'sonic` if missing in config file
Why I did it
Change the path of sonic submodules that point to "Azure" to point to "sonic-net"
How I did it
Replace "Azure" with "sonic-net" on all relevant paths of sonic submodules
Pick up fix for CS00012263713 (mirrored packet with extra VLAN Tag) BRCM SAI 4.3.7.1-1

* [mux] skip mux operations during warm shutdown
- Enhance write_standby.py script to skip actions during warm shutdown.
- Expand the support to BGP service.
- MuX support was added by a previous PR.
- don't skip action during warm recovery
