From: Nipun Gupta <nipun.gupta@nxp.com>


With DEV_RX_OFFLOAD_ERR_PKT_DROP now defined as an offload
capability, and separate RTE_DEV_RX_ERR_PKT_DROP_OFFLOAD_ALL
capability to drop all error packets in hardware, testpmd
showcases this with a new added configuration option
'enable-hw-drop-err-all'.

Hi Nipun,

Some nits. Looks good otherwise.
