1910 * DMA mapping and construction and submission of CTIO Request Entries
1911 * and rendevous for completion are very tightly coupled because we start
1912 * out by knowing (per platform) how much data we have to move, but we
1913 * don't know, up front, how many DMA mapping segments will have to be used
1914 * cover that data, so we don't know how many CTIO Request Entries we
1915 * will end up using. Further, for performance reasons we may want to
1916 * (on the last CTIO for Fibre Channel), send status too (if all went well).
1917 *
1918 * The standard vector still goes through isp_pci_dmasetup, but the callback
1919 * for the DMA mapping routines comes here instead with the whole transfer
1920 * mapped and a pointer to a partially filled in already allocated request
1921 * queue entry. We finish the job.
