Subject: Re: [dpdk-stable] [PATCH v3] net/ixgbe: fix UDP zero checksum error
Date: Mon, 8 Feb 2021 13:48:27 +0000 [thread overview]
Message-ID: <BYAPR11MB3301C18F4A090A13BB2D4F439A8F9@BYAPR11MB3301.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20210204143949.22827-1-haiyue.wang@intel.com>
>
> 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.
>
> Bugzilla ID: 629
> Fixes: af75078fece3 ("first public release")
> Cc: stable@dpdk.org
>
> Reported-by: Paolo Valerio <pvalerio@redhat.com>
> Signed-off-by: Haiyue Wang <haiyue.wang@intel.com>
> ---
> v3: Update the hardware errata doc name and session
> v2: Change the always GOOD checksum to UNKOWN if BAD.
