Subject: Is it correct to report checksum good when there is no checksum?
Date: Thu, 10 Nov 2022 12:25:49 +0300	[thread overview]
Message-ID: <8bea1ef1-1977-f24f-f549-0c2126c23e3c@oktetlabs.ru> (raw)

Hi all,

some drivers report RTE_MBUF_F_RX_IP_CKSUM_GOOD for IPv6 packets.
For me it looks strange, but I see some technical reasons behind.
Documentation in lib/mbuf/rte_mbuf_core.h is a bit vague.
Should UNKNOWN or NONE be used instead?

Thanks,
Andrew.
