is hardware support by a NIC for checksum generation / offloading not quite
usless? the checksumming enging can only be used when UDP/TCP packets
are <= the MTU of the NIC (e.g 1500 bytes).
i expact that UDP/TCP packets are in general bigger than that or is exactly
that wrong and the network protokoll stack splits the data to be transfered
so that each tcp packet is not bigger than the MTU. but whats with UPD there
this wont work.
