                    report a DID_ERROR. Better for an LLD to implement
                    'resid'.
 
+It is recommended that a LLD set 'resid' on data transfers from a SCSI
+target device (e.g. READs). It is especially important that 'resid' is set
+when such data transfers have sense keys of MEDIUM ERROR and HARDWARE ERROR
+(and possibly RECOVERED ERROR). In these cases if a LLD is in doubt how much
+data has been received then the safest approach is to indicate no bytes have
+been received. For example: to indicate that no valid data has been received
+a LLD might use these helpers:
+    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt));
+where 'SCpnt' is a pointer to a scsi_cmnd object. To indicate only three 512
+bytes blocks has been received 'resid' could be set like this:
+    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt) - (3 * 512));
+
 The scsi_cmnd structure is defined in include/scsi/scsi_cmnd.h

+/*
+ * iDiag PCI config space register access methods:
+ *
+ * The PCI config space register accessees of read, write, read-modify-write
+ * for set bits, and read-modify-write for clear bits to SLI4 PCI functions
+ * are provided. In the proper SLI4 PCI function's debugfs iDiag directory,
+ *
+ *      /sys/kernel/debug/lpfc/fn<#>/iDiag
+ *
+ * the access is through the debugfs entry pciCfg:
+ *
+ * 1. For PCI config space register read access, there are two read methods:
+ *    A) read a single PCI config space register in the size of a byte
+ *    (8 bits), a word (16 bits), or a dword (32 bits); or B) browse through
+ *    the 4K extended PCI config space.
+ *
+ *    A) Read a single PCI config space register consists of two steps:
+ *
+ *    Step-1: Set up PCI config space register read command, the command
+ *    syntax is,
+ *
+ *        echo 1 <where> <count> > pciCfg
+ *
+ *    where, 1 is the iDiag command for PCI config space read, <where> is the
+ *    offset from the beginning of the device's PCI config space to read from,
+ *    and <count> is the size of PCI config space register data to read back,
+ *    it will be 1 for reading a byte (8 bits), 2 for reading a word (16 bits
+ *    or 2 bytes), or 4 for reading a dword (32 bits or 4 bytes).
+ *
+ *    Setp-2: Perform the debugfs read operation to execute the idiag command
+ *    set up in Step-1,
+ *
+ *        cat pciCfg
+ *
+ *    Examples:
+ *    To read PCI device's vendor-id and device-id from PCI config space,
+ *
+ *        echo 1 0 4 > pciCfg
+ *        cat pciCfg
+ *
+ *    To read PCI device's currnt command from config space,
+ *
+ *        echo 1 4 2 > pciCfg
+ *        cat pciCfg
+ *
+ *    B) Browse through the entire 4K extended PCI config space also consists
+ *    of two steps:
+ *
+ *    Step-1: Set up PCI config space register browsing command, the command
+ *    syntax is,
+ *
+ *        echo 1 0 4096 > pciCfg
+ *
+ *    where, 1 is the iDiag command for PCI config space read, 0 must be used
+ *    as the offset for PCI config space register browse, and 4096 must be
+ *    used as the count for PCI config space register browse.
+ *
+ *    Step-2: Repeately issue the debugfs read operation to browse through
+ *    the entire PCI config space registers:
+ *
+ *        cat pciCfg
+ *        cat pciCfg
+ *        cat pciCfg
+ *        ...
+ *
+ *    When browsing to the end of the 4K PCI config space, the browse method
+ *    shall wrap around to start reading from beginning again, and again...
+ *
+ * 2. For PCI config space register write access, it supports a single PCI
+ *    config space register write in the size of a byte (8 bits), a word
+ *    (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 2 <where> <count> <value> > pciCfg
+ *
+ *    where, 2 is the iDiag command for PCI config space write, <where> is
+ *    the offset from the beginning of the device's PCI config space to write
+ *    into, <count> is the size of data to write into the PCI config space,
+ *    it will be 1 for writing a byte (8 bits), 2 for writing a word (16 bits
+ *    or 2 bytes), or 4 for writing a dword (32 bits or 4 bytes), and <value>
+ *    is the data to be written into the PCI config space register at the
+ *    offset.
+ *
+ *    Examples:
+ *    To disable PCI device's interrupt assertion,
+ *
+ *    1) Read in device's PCI config space register command field <cmd>:
+ *
+ *           echo 1 4 2 > pciCfg
+ *           cat pciCfg
+ *
+ *    2) Set bit 10 (Interrupt Disable bit) in the <cmd>:
+ *
+ *           <cmd> = <cmd> | (1 < 10)
+ *
+ *    3) Write the modified command back:
+ *
+ *           echo 2 4 2 <cmd> > pciCfg
+ *
+ * 3. For PCI config space register set bits access, it supports a single PCI
+ *    config space register set bits in the size of a byte (8 bits), a word
+ *    (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 3 <where> <count> <bitmask> > pciCfg
+ *
+ *    where, 3 is the iDiag command for PCI config space set bits, <where> is
+ *    the offset from the beginning of the device's PCI config space to set
+ *    bits into, <count> is the size of the bitmask to set into the PCI config
+ *    space, it will be 1 for setting a byte (8 bits), 2 for setting a word
+ *    (16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4 bytes), and
+ *    <bitmask> is the bitmask, indicating the bits to be set into the PCI
+ *    config space register at the offset. The logic performed to the content
+ *    of the PCI config space register, regval, is,
+ *
+ *        regval |= <bitmask>
+ *
+ * 4. For PCI config space register clear bits access, it supports a single
+ *    PCI config space register clear bits in the size of a byte (8 bits),
+ *    a word (16 bits), or a dword (32 bits). The command syntax is,
+ *
+ *        echo 4 <where> <count> <bitmask> > pciCfg
+ *
+ *    where, 4 is the iDiag command for PCI config space clear bits, <where>
+ *    is the offset from the beginning of the device's PCI config space to
+ *    clear bits from, <count> is the size of the bitmask to set into the PCI
+ *    config space, it will be 1 for setting a byte (8 bits), 2 for setting
+ *    a word(16 bits or 2 bytes), or 4 for setting a dword (32 bits or 4
+ *    bytes), and <bitmask> is the bitmask, indicating the bits to be cleared
+ *    from the PCI config space register at the offset. the logic performed
+ *    to the content of the PCI config space register, regval, is,
+ *
+ *        regval &= ~<bitmask>
+ *
+ * Note, for all single register read, write, set bits, or clear bits access,
+ * the offset (<where>) must be aligned with the size of the data:
+ *
+ * For data size of byte (8 bits), the offset must be aligned to the byte
+ * boundary; for data size of word (16 bits), the offset must be aligned
+ * to the word boundary; while for data size of dword (32 bits), the offset
+ * must be aligned to the dword boundary. Otherwise, the interface will
+ * return the error:
+ *
+ *     "-bash: echo: write error: Invalid argument".
+ *
+ * For example:
+ *
+ *     echo 1 2 4 > pciCfg
+ *     -bash: echo: write error: Invalid argument
+ *
+ * Note also, all of the numbers in the command fields for all read, write,
+ * set bits, and clear bits PCI config space register command fields can be
+ * either decimal or hex.
+ *
+ * For example,
+ *     echo 1 0 4096 > pciCfg
+ *
+ * will be the same as
+ *     echo 1 0 0x1000 > pciCfg
+ *
+ * And,
+ *     echo 2 155 1 10 > pciCfg
+ *
+ * will be
+ *     echo 2 0x9b 1 0xa > pciCfg
