Currently PKT_TX_IP_CKSUM is being set into mbuf->ol_flags during fragmentation and reassemble operation implicitly. Because of this, application is forced to use checksum offload whether it is supported by platform or not. Also documentation does not provide any expected value of ol_flags in returned mbuf (reassembled or fragmented) so application will never come to know that which offloads are enabled. So transmission may gets failed for the platforms which does not support checksum offload. Also, IPv6 does not contain any checksum field in header so setting mbuf->ol_flags with PKT_TX_IP_CKSUM is itself invalid. So removing mentioned flag from the library. 2. Enabling PKT_TX_IP_CKSUM into mbuf->ol_flags at fragmentation and reassembly application itself.
