When iwarp was introduced, this should have been modified to return the max inline size based on protocol. This size is cached in the device attributes Fixes: 69ad0e7fe845 ("RDMA/qedr: Add support for iWARP in user space") Link: https://lore.kernel.org/r/20200902165741.8355-8-michal.kalderon@xxxxxxxxxxx Signed-off-by: Michal Kalderon <michal.kalderon@xxxxxxxxxxx> Signed-off-by: Jason Gunthorpe <jgg@xxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/infiniband/hw/qedr/verbs.c b/drivers/infiniband/hw/qedr/verbs.c index 682329789d00d..4408d33646647 100644 --- a/drivers/infiniband/hw/qedr/verbs.c +++ b/drivers/infiniband/hw/qedr/verbs.c @@ -2405,7 +2405,7 @@ int qedr_query_qp(struct ib_qp *ibqp, qp_attr->cap.max_recv_wr = qp->rq.max_wr; qp_attr->cap.max_send_sge = qp->sq.max_sges; qp_attr->cap.max_recv_sge = qp->rq.max_sges; - qp_attr->cap.max_inline_data = ROCE_REQ_MAX_INLINE_DATA_SIZE; + qp_attr->cap.max_inline_data = dev->attr.max_inline; qp_init_attr->cap = qp_attr->cap; qp_attr->ah_attr.type = RDMA_AH_ATTR_TYPE_ROCE;
