From 304cc83807da5fd3044b0f20ed415027e40cd6e7 Mon Sep 17 00:00:00 2001 From: Bhargava Chenna Marreddy Date: Wed, 6 Nov 2024 00:44:35 -0800 Subject: RDMA/bnxt_re: Enhance RoCE SRIOV resource configuration design Refine RoCE SRIOV resource configuration design, using the INITIALIZE_FW's flag as an indication for the new design to the firmware. RoCE driver does not have to provision resources to VF when firmware advertises support for RoCE resource management by NIC driver.
