Summary:Mechanisms are provided, in a data processing system comprising a host system and a network adapter, for processing received frames of data over a network connection. The mechanisms receive, in the host system from the network adapter, a plurality of frames of data. The mechanisms record, by the host system, for each frame in the plurality of frames, a header size associated with the frame over a current predetermined interval. The mechanisms determine, by the host system, a receive buffer address offset for receive buffers in the host system for a next predetermined interval based on the recorded header sizes of the plurality of frames over the current predetermined interval. In addition, the mechanisms configure, by the host system, the network adapter to utilize the receive buffer address offset to perform data transfers with the host system.
