Set the switch settings using the following procedure.
Use any flow control method (Pause, DCBX-CEE, or DCBX-IEEE),
and enable IP routing for RoCE v2. See
for RoCE v2 configuration, or refer to the vendor
switch documents.
If you are using PFC configuration and L3 routing, run RoCE v2 traffic
over the VLAN using a different subnet, and use the RoCE v2 VLAN
GID index.
