Subject: [dpdk-stable] [PATCH 19.11 0/4] Enable Checksum Offloading for NEON vector
Date: Fri, 19 Feb 2021 14:20:37 +0800
Message-ID: <20210219062041.2015421-1-feifei.wang2@arm.com> (raw)

This patch series are mainly to enable checksum offloading for IXGBE NEON
vector PMD, including good and bad checksum flags. In the meanwhile, the
first patch enable VLAN stripping flag for Arm.
Following are the test results for the patches:

NICs: 82599(igb)
Driver: ixgbe(vector)
$:./app/dpdk-testpmd -c 0x3 -w 0002:f9:00.0 -- -i --port-topology=chained
test-pmd> set fwd rxonly
test-pmd> set verbose 1
test-pmd> start

With Patch a:
enable vlan stripping:
src=00:00:00:00:00:02 - dst=00:00:00:00:00:01 - type=0x0800 - length=70 - nb_segs=1 - VLAN tci=0x1
ol_flags: PKT_RX_VLAN PKT_RX_VLAN_STRIPPED

With Patch b:
Packet: IPv4_checksum = 0xee && UDP_checksum = 0xee
src=00:00:00:00:00:02 - dst=00:00:00:00:00:01 - type=0x0800 - length=70 - nb_segs=1
ol_flags: PKT_RX_L4_CKSUM_BAD PKT_RX_IP_CKSUM_BAD

With Patch c:
Packet: IPv4_checksum = correct value && UDP_checksum = correct value
ol_flags: PKT_RX_L4_CKSUM_GOOD PKT_RX_IP_CKSUM_GOOD

Feifei Wang (4):
  a). net/ixgbe: add new flag of stripped VLAN for NEON vector
  b). net/ixgbe: support bad checksum flag for NEON vector
  c). net/ixgbe: support good checksum flag for NEON vector
  d). net/ixgbe: enable IXGBE NEON vector PMD when CHECKSUM need to checksum
