719 * IONIC_TXQ_DESC_OPCODE_CSUM_NONE:
720 * Non-offload send. No segmentation,
721 * fragmentation or checksum calc/insertion is
722 * performed by device; packet is prepared
723 * to send by software stack and requires
724 * no further manipulation from device.
725 *
726 * IONIC_TXQ_DESC_OPCODE_CSUM_PARTIAL:
727 * Offload 16-bit L4 checksum
728 * calculation/insertion. The device will
729 * calculate the L4 checksum value and
730 * insert the result in the packet's L4
731 * header checksum field. The L4 checksum
732 * is calculated starting at @csum_start bytes
733 * into the packet to the end of the packet.
734 * The checksum insertion position is given
735 * in @csum_offset, which is the offset from
736 * @csum_start to the checksum field in the L4
737 * header. This feature is only applicable to
738 * protocols such as TCP, UDP and ICMP where a
739 * standard (i.e. the 'IP-style' checksum)
740 * one's complement 16-bit checksum is used,
741 * using an IP pseudo-header to seed the
742 * calculation. Software will preload the L4
743 * checksum field with the IP pseudo-header
744 * checksum.
745 *
746 * For tunnel encapsulation, @csum_start and
747 * @csum_offset refer to the inner L4
748 * header. Supported tunnels encapsulations
749 * are: IPIP, GRE, and UDP. If the @encap
750 * is clear, no further processing by the
751 * device is required; software will
752 * calculate the outer header checksums. If
753 * the @encap is set, the device will
754 * offload the outer header checksums using
755 * LCO (local checksum offload) (see
756 * Documentation/networking/checksum-offloads.rst
757 * for more info).
758 *
759 * IONIC_TXQ_DESC_OPCODE_CSUM_HW:
760 * Offload 16-bit checksum computation to hardware.
761 * If @csum_l3 is set then the packet's L3 checksum is
762 * updated. Similarly, if @csum_l4 is set the L4
763 * checksum is updated. If @encap is set then encap header
764 * checksums are also updated.
765 *
766 * IONIC_TXQ_DESC_OPCODE_TSO:
767 * Device performs TCP segmentation offload
768 * (TSO). @hdr_len is the number of bytes
769 * to the end of TCP header (the offset to
770 * the TCP payload). @mss is the desired
771 * MSS, the TCP payload length for each
772 * segment. The device will calculate/
773 * insert IP (IPv4 only) and TCP checksums
774 * for each segment. In the first data
775 * buffer containing the header template,
776 * the driver will set IPv4 checksum to 0
777 * and preload TCP checksum with the IP
778 * pseudo header calculated with IP length = 0.
779 *
780 * Supported tunnel encapsulations are IPIP,
781 * layer-3 GRE, and UDP. @hdr_len includes
782 * both outer and inner headers. The driver
783 * will set IPv4 checksum to zero and
784 * preload TCP checksum with IP pseudo
785 * header on the inner header.
786 *
787 * TCP ECN offload is supported. The device
788 * will set CWR flag in the first segment if
789 * CWR is set in the template header, and
790 * clear CWR in remaining segments.
791 * @flags:
792 * vlan:
793 * Insert an L2 VLAN header using @vlan_tci
794 * encap:
795 * Calculate encap header checksum
796 * csum_l3:
797 * Compute L3 header checksum
798 * csum_l4:
799 * Compute L4 header checksum
800 * tso_sot:
801 * TSO start
802 * tso_eot:
803 * TSO end
804 * @num_sg_elems: Number of scatter-gather elements in SG
805 * descriptor
806 * @addr: First data buffer's DMA address
807 * (Subsequent data buffers are on txq_sg_desc)
808 * @len: First data buffer's length, in bytes
809 * @vlan_tci: VLAN tag to insert in the packet (if requested
810 * by @V-bit). Includes .1p and .1q tags
811 * @hdr_len: Length of packet headers, including
812 * encapsulating outer header, if applicable
813 * Valid for opcodes IONIC_TXQ_DESC_OPCODE_CALC_CSUM and
814 * IONIC_TXQ_DESC_OPCODE_TSO. Should be set to zero for
815 * all other modes. For
816 * IONIC_TXQ_DESC_OPCODE_CALC_CSUM, @hdr_len is length
817 * of headers up to inner-most L4 header. For
818 * IONIC_TXQ_DESC_OPCODE_TSO, @hdr_len is up to
819 * inner-most L4 payload, so inclusive of
820 * inner-most L4 header.
821 * @mss: Desired MSS value for TSO; only applicable for
822 * IONIC_TXQ_DESC_OPCODE_TSO
823 * @csum_start: Offset from packet to first byte checked in L4 checksum
