From fdb3680a5a3347572f99a447c83b5fe5c9252879 Mon Sep 17 00:00:00 2001 From: Michael Guralnik Date: Mon, 3 Aug 2020 08:58:49 +0300 Subject: [PATCH] RDMA/mlx5: Fix flow destination setting for RDMA TX flow table For RDMA TX flow table, set destination type to be 'port' and prevent creation of flows with TIR destination. As RDMA TX is an egress flow table the rules on this flow table should not forward traffic back to the NIC and should set the destination to be the port. Without the setting of this destination type flow rules on the RDMA TX flow tables are not created as FW invokes a syndrome for undefined destination for the rule.
