Doc Text:
A flaw was found in the Linux kernel’s Time-Aware Priority Shaper (taprio) scheduler. The issue arises because the taprio scheduler attempts to disable hardware offload, even if it was never enabled, due to an unusual API design. This issue can result in improper handling and potential system instability.
