From e99103602f477c84f31b79779f7544d6e1704593 Mon Sep 17 00:00:00 2001 From: Michael Guralnik Date: Mon, 19 Oct 2020 09:00:56 +0300 Subject: [PATCH] mlx5: Fix wqe size parameter in wqe signature calculation [ Upstream commit 8cde184624d192f7cd61247eec92a3a9b4ba7c7f ] WQE signature calculation requires passing the size of the WQE as a parameter. Current code passes the qpn_ds field as the WQE size which is wrong. Fixing to extract from the qpn_ds the WQE size in bytes and use it for the signature calculations.
