Subject: [dpdk-dev]  [PATCH] examples: remove Rx checksum offload
Date: Sun, 29 Jul 2018 18:14:09 +0530	[thread overview]
Message-ID: <20180729124409.3669-1-jerin.jacob@caviumnetworks.com> (raw)

As of now, application does not check PKT_RX_*_CKSUM_* flags per
packet, so it does not matter DEV_RX_OFFLOAD_CHECKSUM enabled or not.

Removing DEV_RX_OFFLOAD_CHECKSUM offload so that driver can save a few
cycles if possible.
