First Claim
1. A data processing system comprising:
- a host computing device comprising at least one processor;
a network interface device arranged to couple the host computing device to a network, the network interface device comprising a buffer for receiving data for transmission from the host computing device;
wherein the processor is configured to execute instructions to transfer the data for transmission to the buffer; and
the data processing system further comprises;
an indicator store configured to store an indication that at least some of the data for transmission has been transferred to the buffer wherein the indication is associated with a descriptor pointing to the buffer.
