Subject: [dpdk-dev] [PATCH 3/3 v4] app/testpmd: support hardware offload to drop error packets
Date: Thu, 15 Oct 2020 18:53:43 +0530
Message-ID: <20201015132343.4050-3-nipun.gupta@nxp.com> (raw)
In-Reply-To: <20201015132343.4050-1-nipun.gupta@nxp.com>

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'.
