    [SCSI] aacraid: Add new code for PMC-Sierra's SRC based controller family · e8b12f0f
    Mahesh Rajashekhara authored
    Added new hardware device 0x28b interface for PMC-Sierra's SRC based
    controller family.
    
    - new src.c file for 0x28b specific functions
    - new XPORT header required
    - sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT)
    - async. Interface: different inbound queue handling, no outbound I2O
      queue available, using doorbell ("PmDoorBellResponseSent") and
      response buffer on the host ("host_rrq") for status
    - changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending"
      bit to inform about pending AIF, "AifRequest" command to read AIF,
      "NoMoreAifDataAvailable" to mark the end of the AIFs
