A flow rule with a drop action is programmed into the flow steering (FS) table with the DPNI_FS_OPT_DISCARD option so that matching frames are discarded by hardware. The drop action is added to the supported action list, accepted during action verification, configured in the FS action path, handled in the generic flow-set action loop, and cleaned up in the flow destroy path.
