Dchecksum-offloads.rst12 take advantage of checksum offload capabilities of various NICs.
29 The interface for offloading a transmit checksum to a device is explained in
33 checksum defined by the sk_buff fields skb->csum_start and skb->csum_offset.
34 The device should compute the 16-bit ones-complement checksum (i.e. the
35 'IP-style' checksum) from csum_start to the end of the packet, and fill in the
39 the checksum field is included in the checksum computation, thus it can be used
40 to supply any needed corrections to the checksum (such as the sum of the

44 encapsulation is used, the packet may have multiple checksum fields in
