Timo Völker 2927ebde30 sctp, tcp, udp: improve deferred computation of checksums ... When the SCTP, TCP, or UDP implementation send a packet, it does not compute the corresponding checksum but defers that. The network layer will determine whether the network interface selected for the packet has the requested capability and computes the checksum in software, if the selected network interface doesn't have the requested capability. Do this not only for packets being sent by the local SCTP, TCP, and UDP stack, but also when forwarding packets. Furthermore, when such packets are delivered to a local SCTP, TCP, or UDP stack, do not compute or validate the checksum, since such packets never have been on the wire. This allows to support checksum offloading also in the case of local virtual machines or jails. Support for epair, vtnet, and tap interfaces will be added in separate commits.
