…sonic-buildimage into internal 1. Resolve conflicts (introduced by this public PR: [sonic-net#16947](sonic-net#16947)) in `dockers/docker-dhcp-relay/Dockerfile.j2`: ``` <<<<<<< HEAD RUN apt-get install -y dnsmasq gcc python3-dev RUN pip3 install psutil RUN apt-get purge -y gcc python3-dev ======= {% if docker_dhcp_relay_whls.strip() %} # Copy locally-built Python wheel dependencies {{ copy_files("python-wheels/", docker_dhcp_relay_whls.split(' '), "/python-wheels/") }} # Install locally-built Python wheel dependencies {{ install_python_wheels(docker_dhcp_relay_whls.split(' ')) }} {% endif %} >>>>>>> 274d320 ``` Accepted both changes, after resolved: ``` RUN apt-get install -y dnsmasq gcc python3-dev RUN pip3 install psutil RUN apt-get purge -y gcc python3-dev {% if docker_dhcp_relay_whls.strip() %} # Copy locally-built Python wheel dependencies {{ copy_files("python-wheels/", docker_dhcp_relay_whls.split(' '), "/python-wheels/") }} # Install locally-built Python wheel dependencies {{ install_python_wheels(docker_dhcp_relay_whls.split(' ')) }} {% endif %} ``` 2. Because dnsmasq (used for ipv4 dhcp_server previously) exist in internal repo but not exist in public master repo, which would cause new added test case added by [sonic-net#16947](sonic-net#16947) in sonic-config-engine would fail. Also, we expect that dnsmasq is not running if "dhcp_server" feature is enabled. So I **add support for new added test case** and **modify template to avoid run dnsmasq when dhcp_server feature is enabled** in below commit:  Related work items: sonic-net#350, sonic-net#803, sonic-net#2858, sonic-net#16945, sonic-net#16996, sonic-net#17047, sonic-net#17053, sonic-net#17056, sonic-net#17057, sonic-net#17068

- What I did
Updated S6000 CPLD driver to recover if the mux is hung during i2c operation
- How I did it
When i2c read or write fails, the mux is reset using GPIO 10 pin and the operation is tried again.
- How to verify it
Simulated the mux reset and i2c operations. The hung scenario cannot be created in a normal setup. However the code was modified in a way to try mux reset even for successful reads to check if there are any impacts due to reset. The mux reset doesn't cause any issues or have side effects.
