Subject: [PATCH] net/i40e: fix outer checksum flags
Date: Fri, 21 Oct 2022 10:21:51 +0000 [thread overview]
Message-ID: <20221021102151.1000400-1-mingjinx.ye@intel.com> (raw)
When receiving tunnel packets, the testpmd terminal output log shows
'ol_flags' value always as 'RTE_MBUF_F_RX_OUTER_L4_CKSUM_UNKNOWN',
but what we expected should be 'RTE_MBUF_F_RX_OUTER_L4_CKSUM_GOOD'
or 'RTE_MBUF_F_RX_OUTER_L4_CKSUM_BAD'.
Adding 'RTE_MBUF_F_RX_OUTER_L4_CKSUM_GOOD' and
'RTE_MBUF_F_RX_OUTER_L4_CKSUM_BAD' flags for normal path,
which are also added to 'l3_l4_flags_shuf' for AVX2 and AVX512
vector path and 'cksum_flags' for SSE vector path to ensure
the 'ol_flags' can match correct flags.
Fixes: 4861cde46116 ("i40e: new poll mode driver")
Fixes: daa02b5cddbb ("mbuf: add namespace to offload flags")
Fixes: e6a6a138919f ("net/i40e: add AVX512 vector path")
Fixes: dafadd73762e ("net/i40e: add AVX2 Rx function")
Fixes: 9966a00a0688 ("net/i40e: enable bad checksum flags in vector Rx")
Fixes: f3a85f4ce04d ("net/i40e: fix checksum flag in x86 vector Rx")
Fixes: f4356d7ca168 ("net/i40e: eliminate mbuf write on rearm")
