No segmentation, 649 * fragmentation or checksum calc/insertion is 650 * performed by device; packet is prepared 651 * to send by software stack and requires 652 * no further manipulation from device. 653 * 654 * IONIC_TXQ_DESC_OPCODE_CSUM_PARTIAL: 655 * Offload 16-bit L4 checksum 656 * calculation/insertion. The device will 657 * calculate the L4 checksum value and 658 * insert the result in the packet's L4 659 * header checksum field. The L4 checksum 660 * is calculated starting at @csum_start bytes 661 * into the packet to the end of the packet. 662 * The checksum insertion position is given 663 * in @csum_offset, which is the offset from 664 * @csum_start to the checksum field in the L4 665 * header. This feature is only applicable to 666 * protocols such as TCP, UDP and ICMP where a 667 * standard (i.e. the 'IP-style' checksum) 668 * one's complement 16-bit checksum is used, 669 * using an IP pseudo-header to seed the 670 * calculation. Software will preload the L4 671 * checksum field with the IP pseudo-header 672 * checksum. 673 * 674 * For tunnel encapsulation, @csum_start and 675 * @csum_offset refer to the inner L4 676 * header. Supported tunnels encapsulations 677 * are: IPIP, GRE, and UDP. If the @encap 678 * is clear, no further processing by the 679 * device is required; software will 680 * calculate the outer header checksums. If 681 * the @encap is set, the device will 682 * offload the outer header checksums using 683 * LCO (local checksum offload) (see 684 * Documentation/networking/checksum-offloads.rst 685 * for more info). 686 * 687 * IONIC_TXQ_DESC_OPCODE_CSUM_HW: 688 * Offload 16-bit checksum computation to hardware. 689 * If @csum_l3 is set then the packet's L3 checksum is 690 * updated. Similarly, if @csum_l4 is set the the L4 691 * checksum is updated. If @encap is set then encap header 692 * checksums are also updated. 693 * 694 * IONIC_TXQ_DESC_OPCODE_TSO: 695 * Device preforms TCP segmentation offload 696 * (TSO). @hdr_len is the number of bytes 697 * to the end of TCP header (the offset to 698 * the TCP payload). @mss is the desired 699 * MSS, the TCP payload length for each 700 * segment. The device will calculate/ 701 * insert IP (IPv4 only) and TCP checksums 702 * for each segment. In the first data 703 * buffer containing the header template, 704 * the driver will set IPv4 checksum to 0 705 * and preload TCP checksum with the IP 706 * pseudo header calculated with IP length = 0. 707 * 708 * Supported tunnel encapsulations are IPIP, 709 * layer-3 GRE, and UDP. @hdr_len includes 710 * both outer and inner headers. The driver 711 * will set IPv4 checksum to zero and 712 * preload TCP checksum with IP pseudo 713 * header on the inner header. 714 * 715 * TCP ECN offload is supported. The device 716 * will set CWR flag in the first segment if 717 * CWR is set in the template header, and 718 * clear CWR in remaining segments. 719 * @flags: 720 * vlan: 721 * Insert an L2 VLAN header using @vlan_tci 722 * encap: 723 * Calculate encap header checksum 724 * csum_l3: 725 * Compute L3 header checksum 726 * csum_l4: 727 * Compute L4 header checksum 728 * tso_sot: 729 * TSO start 730 * tso_eot: 731 * TSO end 732 * @num_sg_elems: Number of scatter-gather elements in SG 733 * descriptor 734 * @addr: First data buffer's DMA address 735 * (Subsequent data buffers are on txq_sg_desc) 736 * @len: First data buffer's length, in bytes 737 * @vlan_tci: VLAN tag to insert in the packet (if requested 738 * by @V-bit).
