devlink: Add 'total_vfs' generic device param NICs are typically configured with total_vfs=0, forcing users to rely on external tools to enable SR-IOV (a widely used and essential feature). Add total_vfs parameter to devlink for SR-IOV max VF configurability. Enables standard kernel tools to manage SR-IOV, addressing the need for flexible VF configuration.
