+ * no further manipulation from device.
+ *
+ * IONIC_TXQ_DESC_OPCODE_CSUM_PARTIAL:
+ *
+ * Offload 16-bit L4 checksum
+ * calculation/insertion. The device will
+ * calculate the L4 checksum value and
+ * insert the result in the packet's L4
+ * header checksum field. The L4 checksum
+ * 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. 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.txt 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 the L4
+ * checksum is updated. If @encap is set then encap header
+ * checksums are also updated.
+ *
+ * IONIC_TXQ_DESC_OPCODE_TSO:
+ *
+ * Device preforms 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 TXQ_DESC_OPCODE_CALC_CSUM and
+ * TXQ_DESC_OPCODE_TSO. Should be set to zero for
+ * all other modes. For
+ * TXQ_DESC_OPCODE_CALC_CSUM, @hdr_len is length
+ * of headers up to inner-most L4 header. For
+ * 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
