Re: [PATCH rdma-next v3 5/5] RDMA/mana_ib: Poll UD completions and flush software error QPs

[sashiko-bot@kernel.org]

> From: Konstantin Taranov <kotaranov@microsoft.com>
> 
> Build UD and GSI work completions directly from each hardware CQE and
> the corresponding published shadow entry. Decode receive length, source
> QP and immediate data directly, removing byte_len, src_qpn and cached
> status from the common shadow header. Introduce a WC-budgeted poll context
> with a cached CQE for RC polling.
> 
> Match UD send and receive CQEs against the low 24 bits of the posted WQE
> offset before consuming the shadow entry.
> 
> Honor the QP's IB_SIGNAL_ALL_WR policy together with IB_SEND_SIGNALED when
> posting sends, and mark unsignaled entries with MANA_WQ_NO_SIGNAL_WC.
> Since successful unsignaled sends do not generate CQEs, locate the matching
> entry through the unsignaled prefix before retiring any WRs.
> [ ... ]
> Automatic error-list insertion and CQ notification on a successful ERR
> transition are introduced separately with RC support. Hardware error-CQE
> decoding and deferred QP error handling also remain in the RC series.
> 
> Signed-off-by: Konstantin Taranov <kotaranov@microsoft.com>
