* is calculated starting at @csum_start bytes
* into the packet to the end of the packet.
* The checksum insertion position is given
* in @csum_offset, which is the offset from
* @csum_start to the checksum field in the L4
* header. This feature is only applicable to
* protocols such as TCP, UDP and ICMP where a
* standard (i.e. the 'IP-style' checksum)
* one's complement 16-bit checksum is used,
* using an IP pseudo-header to seed the
* calculation. Software will preload the L4
* checksum field with the IP pseudo-header
* checksum.
*
* For tunnel encapsulation, @csum_start and
* @csum_offset refer to the inner L4
* header. Supported tunnels encapsulations
* are: IPIP, GRE, and UDP. If the @encap
* is clear, no further processing by the
* device is required; software will
* calculate the outer header checksums. If
* the @encap is set, the device will
* offload the outer header checksums using
* LCO (local checksum offload) (see
* Documentation/networking/checksum-offloads.rst
* for more info).
*
* IONIC_TXQ_DESC_OPCODE_CSUM_HW:
* Offload 16-bit checksum computation to hardware.
* If @csum_l3 is set then the packet's L3 checksum is
* updated. Similarly, if @csum_l4 is set the L4
* checksum is updated. If @encap is set then encap header
* checksums are also updated.
*
* IONIC_TXQ_DESC_OPCODE_TSO:
* Device performs TCP segmentation offload
* (TSO). @hdr_len is the number of bytes
* to the end of TCP header (the offset to
* the TCP payload). @mss is the desired
* MSS, the TCP payload length for each
* segment. The device will calculate/
* insert IP (IPv4 only) and TCP checksums
* for each segment. In the first data
* buffer containing the header template,
* the driver will set IPv4 checksum to 0
* and preload TCP checksum with the IP
* pseudo header calculated with IP length = 0.
*
* Supported tunnel encapsulations are IPIP,
* layer-3 GRE, and UDP. @hdr_len includes
* both outer and inner headers. The driver
* will set IPv4 checksum to zero and
* preload TCP checksum with IP pseudo
* header on the inner header.
*
* TCP ECN offload is supported. The device
* will set CWR flag in the first segment if
* CWR is set in the template header, and
* clear CWR in remaining segments.
* @flags:
* vlan:
* Insert an L2 VLAN header using @vlan_tci
* encap:
* Calculate encap header checksum
* csum_l3:
* Compute L3 header checksum
* csum_l4:
* Compute L4 header checksum
* tso_sot:
* TSO start
* tso_eot:
* TSO end
* @num_sg_elems: Number of scatter-gather elements in SG
* descriptor
* @addr: First data buffer's DMA address
* (Subsequent data buffers are on txq_sg_desc)
* @len: First data buffer's length, in bytes
* @vlan_tci: VLAN tag to insert in the packet (if requested
* by @V-bit). Includes .1p and .1q tags
* @hdr_len: Length of packet headers, including
* encapsulating outer header, if applicable
* Valid for opcodes IONIC_TXQ_DESC_OPCODE_CALC_CSUM and
* IONIC_TXQ_DESC_OPCODE_TSO. Should be set to zero for
* all other modes. For
* IONIC_TXQ_DESC_OPCODE_CALC_CSUM, @hdr_len is length
* of headers up to inner-most L4 header. For
* IONIC_TXQ_DESC_OPCODE_TSO, @hdr_len is up to
* inner-most L4 payload, so inclusive of
* inner-most L4 header.
* @mss: Desired MSS value for TSO; only applicable for
* IONIC_TXQ_DESC_OPCODE_TSO
* @csum_start: Offset from packet to first byte checked in L4 checksum
* @csum_offset: Offset from csum_start to L4 checksum field
