5c28f213 559 * struct ionic_txq_desc - Ethernet Tx queue descriptor format
fbfb8031
SN		 560 * @opcode: Tx operation, see TXQ_DESC_OPCODE_*:
561 *
562 * IONIC_TXQ_DESC_OPCODE_CSUM_NONE:
563 *
564 * Non-offload send. No segmentation,
565 * fragmentation or checksum calc/insertion is
566 * performed by device; packet is prepared
567 * to send by software stack and requires
568 * no further manipulation from device.
569 *
570 * IONIC_TXQ_DESC_OPCODE_CSUM_PARTIAL:
571 *
572 * Offload 16-bit L4 checksum
573 * calculation/insertion. The device will
574 * calculate the L4 checksum value and
575 * insert the result in the packet's L4
576 * header checksum field. The L4 checksum
577 * is calculated starting at @csum_start bytes
578 * into the packet to the end of the packet.
579 * The checksum insertion position is given
580 * in @csum_offset. This feature is only
581 * applicable to protocols such as TCP, UDP
582 * and ICMP where a standard (i.e. the
583 * 'IP-style' checksum) one's complement
584 * 16-bit checksum is used, using an IP
585 * pseudo-header to seed the calculation.
586 * Software will preload the L4 checksum
587 * field with the IP pseudo-header checksum.
588 *
589 * For tunnel encapsulation, @csum_start and
590 * @csum_offset refer to the inner L4
591 * header. Supported tunnels encapsulations
592 * are: IPIP, GRE, and UDP. If the @encap
593 * is clear, no further processing by the
594 * device is required; software will
595 * calculate the outer header checksums. If
596 * the @encap is set, the device will
597 * offload the outer header checksums using
598 * LCO (local checksum offload) (see
599 * Documentation/networking/checksum-
600 * offloads.txt for more info).
601 *
602 * IONIC_TXQ_DESC_OPCODE_CSUM_HW:
603 *
604 * Offload 16-bit checksum computation to hardware.
605 * If @csum_l3 is set then the packet's L3 checksum is
606 * updated. Similarly, if @csum_l4 is set the the L4
607 * checksum is updated. If @encap is set then encap header
608 * checksums are also updated.
609 *
610 * IONIC_TXQ_DESC_OPCODE_TSO:
611 *
612 * Device preforms TCP segmentation offload
613 * (TSO). @hdr_len is the number of bytes
614 * to the end of TCP header (the offset to
615 * the TCP payload). @mss is the desired
616 * MSS, the TCP payload length for each
617 * segment. The device will calculate/
618 * insert IP (IPv4 only) and TCP checksums
619 * for each segment. In the first data
620 * buffer containing the header template,
621 * the driver will set IPv4 checksum to 0
622 * and preload TCP checksum with the IP
623 * pseudo header calculated with IP length = 0.
624 *
625 * Supported tunnel encapsulations are IPIP,
626 * layer-3 GRE, and UDP. @hdr_len includes
627 * both outer and inner headers. The driver
628 * will set IPv4 checksum to zero and
629 * preload TCP checksum with IP pseudo
630 * header on the inner header.
631 *
632 * TCP ECN offload is supported. The device
633 * will set CWR flag in the first segment if
634 * CWR is set in the template header, and
635 * clear CWR in remaining segments.
636 * @flags:
637 * vlan:
638 * Insert an L2 VLAN header using @vlan_tci.
639 * encap:
640 * Calculate encap header checksum.
641 * csum_l3:
642 * Compute L3 header checksum.
643 * csum_l4:
644 * Compute L4 header checksum.
645 * tso_sot:
646 * TSO start
647 * tso_eot:
648 * TSO end
649 * @num_sg_elems: Number of scatter-gather elements in SG
650 * descriptor
651 * @addr: First data buffer's DMA address.
652 * (Subsequent data buffers are on txq_sg_desc).
653 * @len: First data buffer's length, in bytes
654 * @vlan_tci: VLAN tag to insert in the packet (if requested
655 * by @V-bit). Includes .1p and .1q tags
656 * @hdr_len: Length of packet headers, including
657 * encapsulating outer header, if applicable.
658 * Valid for opcodes TXQ_DESC_OPCODE_CALC_CSUM and
659 * TXQ_DESC_OPCODE_TSO. Should be set to zero for
660 * all other modes. For
661 * TXQ_DESC_OPCODE_CALC_CSUM, @hdr_len is length
662 * of headers up to inner-most L4 header. For
663 * TXQ_DESC_OPCODE_TSO, @hdr_len is up to
664 * inner-most L4 payload, so inclusive of
665 * inner-most L4 header.
666 * @mss: Desired MSS value for TSO. Only applicable for
667 * TXQ_DESC_OPCODE_TSO.
668 * @csum_start: Offset into inner-most L3 header of checksum
669 * @csum_offset: Offset into inner-most L4 header of checksum
