From: Long Li <longli@microsoft.com> Carry the XDP program with the queue set and install its per-queue references before redirecting RSS. This keeps the RX buffer layout and program together during publication and rollback. Do not replace the live program during allocation. This also avoids the pre-existing failed-preallocation stale-pointer bug; its standalone net fix is linked below. This full rebuild temporarily keeps both sets of SQ/RQ/CQ objects, RX buffers and page pools live. The port-owned EQ pool is shared, not doubled. Device resource limits may reject this temporary peak; allocation failure preserves the live queues and configuration. Reserve RAW-QP admission under vport_mutex for the entire live replacement, including unpublished queues, fail-close and scratch cleanup. Preserve validation, no-op and down-port behavior.
