 *                      pseudo-header to seed the calculation.

 *                      For tunnel encapsulation, @csum_start and

 *                      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
 *                TXQ_DESC_OPCODE_TSO.
 * @csum_start:   Offset into inner-most L3 header of checksum
 * @csum_offset:  Offset into inner-most L4 header of checksum

 * The dev commands are intended only to be used during driver initialization,

 * via the rdma admin queue, and will support a more complete interface
 * providing scatter gather lists for larger, scattered queue buffers and

/**
 * struct doorbell - Doorbell register layout
 * @p_index: Producer index
 * @ring:    Selects the specific ring of the queue to update.
 *           Type-specific meaning:
 *              ring=0: Default producer/consumer queue.
 *              ring=1: (CQ, EQ) Re-Arm queue.  RDMA CQs
 *              send events to EQs when armed.  EQs send
 *              interrupts when armed.
 * @qid:     The queue id selects the queue destination for the
 *           producer index and flags.
