Re: [dpdk-dev] [PATCH v3] net/ixgbe: fix UDP zero checksum error
From: Ananyev, Konstantin <hidden>
Date: 2021-02-08 13:48:38
There is an 82599 errata that UDP frames with a zero checksum are
incorrectly marked as checksum invalid by the hardware. This was
leading to misleading PKT_RX_L4_CKSUM_BAD flag.
This patch changes the bad UDP checksum to PKT_RX_L4_CKSUM_UNKNOWN,
so the software application will then have to recompute the checksum
itself if needed.
