Currently PKT_TX_IP_CKSUM is being set into mbuf->ol_flags\nduring fragmentation and reassemble operation implicitly.\nBecause of this, application is forced to use checksum offload\nwhether it is supported by platform or not.\n    \nAlso documentation does not provide any expected value of ol_flags\nin returned mbuf (reassembled or fragmented) so application will never\ncome to know that which offloads are enabled. So transmission may gets\nfailed for the platforms which does not support checksum offload.\n    \nAlso, IPv6 does not contain any checksum field in header so setting\nmbuf->ol_flags with PKT_TX_IP_CKSUM is itself invalid.\n\nSo removing mentioned flag from the library.\n\n2. Enabling PKT_TX_IP_CKSUM into mbuf->ol_flags at fragmentation\n   and reassembly application itself.\n\nSunil Kumar Kori (3):\n  lib/librte_ip_frag: Remove PKT_TX_IP_CKSUM offload flags\n  examples/ip_fragmentation: Enabling IP checksum offload in mbuf\n  examples/ip_reassembly: Enabling IP checksum offload in mbuf\n\n examples/ip_fragmentation/main.c            | 7 +++++--\n examples/ip_reassembly/main.c               | 6 ++++++\n lib/librte_ip_frag/rte_ipv4_fragmentation.c | 1 -\n lib/librte_ip_frag/rte_ipv4_reassembly.c    | 3 ---\n lib/librte_ip_frag/rte_ipv6_reassembly.c    | 3 ---\n 5 files changed, 11 insertions(+), 9 deletions(-)"
