Conntrack need not verify the checksum of incoming packets if it is validated
by DPDK physical NIC ports.
Also make use the DPDK rx checksum mask bits along with flags while validating
the reported hardware checksum state.
v5->v6
(No functional changes in this version)
- Rebased on master
- Added Acked-by
v4->v5
(No functional changes in this version)
- Rebased on latest master.
- Added Darrel as co-author and removed the 'suggested by' tag.
- Moved the bad checksum validate functions from patch-2 to patch-1.
v3->v4
- Rebased on latest master
- Invoke 'checksum_valid' function only when checksum is not validated in
hardware. Check the 'validate_checksum' flag first to invoke the
'checksum_valid' function accordingly.
v2->v3
- Rebased on latest master.
- Updated the existing DPDK checksum validation function to honor hw offload
masks along with checksum bits reported by hardware.
- As suggested by Darrel, Introduced new functions to validate bad checksum
reported by DPDK.
- As proposed by Darrel, modified the conntrack checksum validation to check
bad checksum first on received packets.
- Modified conntrack to validate checksum in software only when it failed to
- do in hardware. Changed the logic to validate bad and good checksum flags
reported by hardware.
- Added tag 'Suggested-by: Darrell Ball <db...@vmware.com>'.
- Removed Acked, Tested by tags from Antonio as the changes has been
modified afterwards.
v1->v2
- Rebased on master
- Added acked-by and tested-by tags in commit message
