.SH NAME
efadv_wr_set_processing_hints \- Set processing hints on the current
work request
.SH SYNOPSIS
.IP
.EX
#include \f[B]<infiniband/efadv.h>\f[R]

static \f[B]inline\f[R] void efadv_wr_set_processing_hints(
    \f[B]struct\f[R] efadv_qp *efadv_qp,
    uint32_t hints);
.EE
.SH DESCRIPTION
\f[B]efadv_wr_set_processing_hints()\f[R] sets processing hints on the
current work request being built.
Hints allow the application to communicate intended usage patterns to
the device, which may use them to optimize processing.
.PP
This function is a work request setter and must be called after the work
request opcode function (e.g.\ \f[B]ibv_wr_send()\f[R]) and before
\f[B]ibv_wr_complete()\f[R] or the next work request opcode call.
.PP
Use \f[B]efadv_qp_from_ibv_qp_ex()\f[R] to get the efadv_qp for
accessing this interface.
.PP
The QP must be created with \f[B]EFADV_WR_EX_WITH_PROCESSING_HINTS\f[R]
set in \f[I]efadv_qp_init_attr.wr_flags\f[R] to use this function.
.PP
The \f[I]hints\f[R] argument is a bitmask of
\f[B]efadv_wr_processing_hint\f[R] values:
.IP
.EX
\f[B]enum\f[R] efadv_wr_processing_hint {
    EFADV_WR_PROCESSING_HINT_BURST_PPS_SENSITIVE = 1 << 0,
};
.EE
.TP
\f[I]EFADV_WR_PROCESSING_HINT_BURST_PPS_SENSITIVE\f[R]
Optimize for throughput in bursty, packet\-rate sensitive workloads.
