Walkthrough

Two new kernel configuration options, CONFIG_USB_ETH and CONFIG_USB_CDC_COMPOSITE, were added as modules in the Linux kernel configuration for the k3-beagle-edge platform. These options enable support for USB Ethernet devices and composite CDC USB devices. No existing configuration options were removed or modified, and there were no changes to exported or public entity declarations.

config/kernel/linux-k3-beagle-edge.config (2)

721-721: Approve enabling USB Ethernet module (CONFIG_USB_ETH=m)
This adds support for USB Ethernet devices as a loadable module on the k3-beagle-edge. Confirm that CONFIG_USB_ETH is defined in the kernel’s Kconfig and pulls in the correct driver.

Run the following script to verify the option exists:

#!/bin/bash
# Verify CONFIG_USB_ETH is defined in drivers/net/usb/Kconfig
grep -R "config USB_ETH" -n drivers/net/usb

---

723-723: ```shell
#!/bin/bash

Search entire repository for the CDC composite USB gadget config entry

grep -R "config USB_CDC_COMPOSITE" -n .

Fallback: search for any mention of CDC_COMPOSITE in Kconfig files

grep -R "CDC_COMPOSITE" -n . | grep -i Kconfig

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Explain this complex logic.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai explain this code block.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and explain its main purpose.`
