> byte_len, src_qpn and the cached status until direct-CQE polling replaces
> their readers. Use this common entry for both send and receive queues,
> including allocation, posting, CQE handling and WC generation. Derive
> the receive WC opcode from the queue rather than storing it per WQE.
> 
> Publish initialized entries and release consumed entries with matching
> release/acquire operations so posting and polling can run on different
> CPUs. Retain the legacy completion cursor until direct-CQE polling and
> software flush lists replace it.
