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.

Memory transfer optimization of network adapter data placement when performing header-data split operations

A technique for accessing features of a hardware adapter includes reading a first key from a hardware adapter and attempting to decrypt the first key with a second key. In response to the second key successfully decrypting the first key: encrypted code from the hardware adapter is read; the encrypted code is decrypted with the decrypted first key to generate unencrypted code; and a default code in an executable flash sector of the hardware adapter is over-written with the unencrypted code. In this case, the unencrypted code facilitates access to at least one feature of the hardware adapter that is customer specific. In response to the second key not successfully decrypting the first key, the default code in the executable flash sector of the hardware adapter is not over-written. In this case, the default code facilitates access to one or more features that are not customer specific.
