Abstract
A host memory location pointer is posted from a host device to a network interface card (NIC) attached to the host device prior to receipt at the NIC of data to be placed in the host memory location corresponding to the pointer. Posting the host memory location pointer serves to surrender ownership of the host memory location from the host device to the NIC. Data received at the NIC is placed in the host memory location corresponding to the pointer. Furthermore, the NIC operates to prevent placement of the data in a portion of the host memory where data has been previously placed by the NIC. Also, the host device operates to re-assume ownership of the portion of the host memory having data placed therein by the NIC without actively reclaiming ownership of the portion of the host memory location from the NIC.
