... CRC and markers), and transmit the data, thereby relieving the host CPU from these time-consuming operations. On the receive path, the BCM57710 processes the frame up to the highest layer present for TCP, iSCSI, or RDMA strip headers, and special fields (e.g., CRC and markers) and places the data with zero copy in the best buffer available for the data— ...
