       error_count Error Count: a 64-bit incrementing error count, indicating a unique identifier
                   for this error. The error count starts at 1h, is incremented for  each  unique
                   error  log  entry, and is retained across power off conditions.  A value of 0h
                   indicates an invalid entry; this value is used when there are lost entries  or
                   when  there are fewer errors than the maximum number of entries the controller
                   supports. If the value of this field is FFFFFFFFh, then the field shall be set
                   to 1h when incremented (i.e., rolls over to 1h). Prior to NVMe 1.4, processing
                   of incrementing beyond FFFFFFFFh is unspecified.

       sqid        Submission Queue ID: indicates the Submission Queue Identifier of the  command
                   that the error information is associated with. If the error is not specific to
                   a particular command, then this field shall be set to FFFFh.

       cmdid       Command ID: indicates the Command Identifier of the command that the error  is
                   associated  with.  If  the error is not specific to a particular command, then
                   this field shall be set to FFFFh.

       status_field
                   Bits 15-1: Status Field: indicates the  Status  Field  for  the  command  that
                   completed.  If  the  error  is not specific to a particular command, then this
                   field reports the most  applicable  status  value.   Bit  0:  Phase  Tag:  may
                   indicate the Phase Tag posted for the command.

       parm_error_location
                   Parameter  Error Location: indicates the byte and bit of the command parameter
                   that the error is associated with,  if  applicable.  If  the  parameter  spans
                   multiple  bytes or bits, then the location indicates the first byte and bit of
                   the parameter.  Bits 10-8: Bit in command that  contained  the  error.   Valid
                   values are 0 to 7.  Bits 7-0: Byte in command that contained the error.  Valid
                   values are 0 to 63.

       lba         LBA: This field indicates the first LBA that experienced the error  condition,
                   if applicable.

       nsid        Namespace:  This  field  indicates the NSID of the namespace that the error is
                   associated with, if applicable.

       vs          Vendor Specific Information Available: If there is additional vendor  specific
                   error  information  available,  this  field  provides  the log page identifier
                   associated with that  page.  A  value  of  0h  indicates  that  no  additional
                   information is available. Valid values are in the range of 80h to FFh.

       trtype      Transport  Type  (TRTYPE):  indicates  the  Transport  Type  of  the transport
                   associated with the error. The values in this field are the same as the TRTYPE
                   values in the Discovery Log Page Entry. If the error is not transport related,
                   this field shall be cleared to 0h. If the error  is  transport  related,  this
                   field shall be set to the type of the transport - see enum nvme_trtype.

       rsvd        Reserved

       cs          Command   Specific   Information:   This   field   contains  command  specific
                   information.  If  used,  the  command  definition  specifies  the  information
                   returned.
