Johannes, Thank you for your feedback. Our intention is to implement the changes ourselves. I apologize if it appeared otherwise; we are not seeking someone else to implement the changes, but rather making sure that we are on the right track. Thanks for confirming that kernel module changes will likely be necessary to apply EDCA parameters from userspace. I intend to build a user-mode Linux kernel for further debugging and add checks for NULL, following your advice. Additionally, I have been utilizing the "nlmon" interface for debugging purposes (https://jvns.ca/blog/2017/09/03/debugging-netlink-requests/) . The code snippet I gave was just a primary attempt. When calling the NL80211_CMD_EPCS_ENABLE, we will need to include the link_id and EDCA settings as parameters. We plan to use NL80211_ATTR_WIPHY_TXQ_PARAMS per your suggestion. Thanks again, Jason
