Subject: [dpdk-dev] [PATCH] net/octeontx2: offload bad L4 checksum detection
Date: Fri, 1 May 2020 15:23:28 +0530 [thread overview]
Message-ID: <1588326809-17372-1-git-send-email-agupta3@marvell.com> (raw)
From: Amit Gupta <agupta3@marvell.com>
On detecting outer L4 checksum as bad, both outer and
inner checksums are marked as bad. No need to explicitly
check inner L4 checksum in this case.
Outer L4 UDP checksum error => PKT_RX_OUTER_L4_CKSUM_BAD
and PKT_RX_L4_CKSUM_BAD
Inner L4 UDP checksum error => PKT_RX_L4_CKSUM_BAD
Fixes: 41fe7a3a11fd ("net/octeontx2: offload bad L2/L3/L4 UDP lengths detection")
