net/octeontx2: allow VFs to enable back pressure
Allow VFs to enable backpressure for performance reasons. The backpressure control is with kernel AF driver that will enable backpressure even if one PF/VF requests it and disable it only after all the PFs/VFs request for disable. Signed-off-by: Nithin Dabilpuram <ndabilpuram@marvell.com>
