Before doing so, I recommend turning off VF probing. Otherwise the VFs will all make IPoIB interfaces, which probably isn't what you want. This setting is per PF. text/html 2026-08-09T06:23:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.naptastic.com/nndocs/infiniband/connectx-3?rev=1786256626&do=diff SR-IOV I don't think this can be made to work. The number of VFs per port is controlled when the module is loaded: options mlx4_core num_vfs=3,3,0 probe_vf=3,3,0 The triplet is the number of VFs for port 1, the number of VFs for port 2, and the number of VFs that contain both ports. text/html 2026-08-08T21:04:03+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.naptastic.com/nndocs/infiniband/connectx-4?rev=1786223043&do=diff Firmware Configuration [root]@[southpark][13:32:34][~]# mlxconfig -d 06:00.0 q Device #1: ---------- Device type: ConnectX4 Name: MCX456A-FCA_Ax Description: ConnectX-4 VPI adapter card; FDR IB (56Gb/s) and 40GbE; dual-port QSFP28; PCIe3.0 x16; ROHS R6 Device: 06:00.0 Configurations: Next Boot PORT_OWNER True(1) ALLOW_RD_COUNT…
