MSI EdgeXpert ethernet EEE link flapping fix

The onboard Realtek 10G NIC (driven by the in-tree r8169 module) can cycle its link up and down because of Energy Efficient Ethernet (EEE). Disabling EEE completely is the fix; pinning the link speed is added hardening. See why this works rather than swapping the driver and why pin the speed. The interface here is enP7s7 — confirm yours. Run as root.

No extra firmware package is needed: the rtl_nic/ firmware the driver loads ships

Comments in Markdown

Sometimes it is useful to put comments in a markdown file. A good example is when creating a "template" markdown file that is then completed by somebody.

Since this is demonstrating comments in markdown, you will need to view the raw file to see the example.

Why You Should Use YAML as YAML with Ansible

As a software engineer I require a consistent style in any configuration or code. Static analysis and style checking are very important for project health. These procedures have a place in any project.

With Ansible, parameters can be written as fully expanded YAML dictionaries or as condensed key=value pairs. It is left up to the user to decide between the styles. Working on playbooks, roles, or tasks that use both styles can be tedious compared to just using expanded YAML dictionaries.

Something that I have recently decided on is to use YAML as YAML with Ansible. I use fully expanded YAML dictionaries everywhere now. My recommendation is that you try it, too.
