From ea30b966f7dd6bcfb20c98a7f99608c7bb10bfac Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Wed, 21 Jun 2017 09:26:28 +0300 Subject: IB/mlx4: Add inline-receive support When inline-receive is enabled, the HCA may write received data into the receive WQE. Inline-receive is enabled by setting its matching bit in the QP context and each single-packet message with payload not exceeding the receive WQE size will be delivered to the WQE. The completion report will indicate that the payload was placed to the WQE. It includes: 1) Return maximum supported size of inline-receive by the hardware in query_device vendor's data part. 2) Enable the feature when requested by the vendor data input.
