NAME

       int6kmdio2 - Qualcomm Atheros 32-bit MDIO Register Editor

SYNOPSIS

       int6kmdio2 [options] [device] [device] [...]

DESCRIPTION

       Read  or  write  the  global MDIO registers on an Atheros powerline device using multiple VS_MDIO_COMMAND
       vendor-specific management messages.  Commands are entered using 32-bit register  and  data  values  then
       converted  to  three equivalent 16-bit commands.  The default operation is to read a register.  Registers
       are written only if data is specified on the command line.

       This program writes MDIO instructions using 802.3ae Clause 45  (address,  data  and  mask)  format.   See
       program  int6kmdio  for a similar program to write instructions using 802.3 Clause 22 (phy, reg, data and
       mask) format.

       This program is deprecated and may be removed in future toolkit releases.  Use program plcmdio32 instead.

OPTIONS

       -a address
              The 19-bit global register  address.   Some  devices  may  not  support  all  possible  addresses.
              Addresses may be expressed in decimal, hexadecimal or binary notation.  Hexadecimal values must be
              prefixed with "0x" or "0X".  Binary values must be prefixed with "0b" or "0B".

       -d data
              A  32-bit  data  value  to  be  inserted into the specified register.  The specified data value is
              written when this option is present; otherwise the specified register is read and the  content  is
              displayed.   Data values may be expressed in decimal, hexadecimal or binary notation.  Hexadecimal
              values are prefixed with "0x" or "0X".  Binary values are prefixed with "0b" or "0B".

       -e     Redirects stderr messages to stdout.  By convention status  and  error  messages  are  printed  on
              stderr while primary program output is printed on stdout.  This option prints all output on stdout
              in cases where this is desired.

       -h     Write high order-byte before low-order byte.  This option is only useful on some architectures.

       -i interface
              Select  the  host  Ethernet  interface.   All  requests  are sent via this host interface and only
              reponses received via this host interface are recognized.  The default interface is  eth1  because
              most  people  use eth0 as their principle network connection; however, if environment string "PLC"
              is defined then it takes precedence over the default interface.  This option then takes precedence
              over either default.

       -q     Suppresses status messages on stderr.

       -v     Prints additional information on stdout.  In  particular,  this  option  dumps  outgoing  Ethernet
              packets on stdout.

       -?,--help
              Displays  program help information on stderr.  This option takes precedence over all other options
              on the command line except version information.

       -!,--version
              Displays program version information on stderr.  This  option  takes  precedence  over  all  other
              options on the command line except help information.  Use this option when sending screen dumps to
              Atheros technical staff.

ARGUMENTS

       device The  MAC  address of some powerline device.  More than one address may be specified.  If more than
              one address is specified then operations are performed  on  each  device  in  turn.   The  default
              address is local.  See DEVICES for information about symbolic device addresses.

DEVICES

       Powerline  devices  use  Ethernet  Media Access Control (MAC) addresses.  A MAC address is a 48-bit value
       entered as 12 hexadecimal digits in upper, lower or mixed character case.  Octets may be  separated  with
       colons  for  clarity.  For example, "00b052000001", "00:b0:52:00:00:01" and "00b052:000001" are valid and
       equivalent.

       The following MAC addresses are special and may be entered by name instead of number.

       all    Same as "broadcast".

       broadcast
              A synonym for the Ethernet broadcast address,  FF:FF:FF:FF:FF:FF.   All  devices,  whether  local,
              remote  or  foreign recognize messages sent to this address.  A remote device is any device at the
              far end of a powerline connection.  A foreign device is any device not manufactured by Atheros.

       local  A  synonym  for  the  Qualcomm  Atheros  vendor   specific   Local   Management   Address   (LMA),
              00:B0:52:00:00:01.   All  local  Atheros  devices  recognize  this  address but remote and foreign
              devices do not.  A remote device is any device at the  far  end  of  a  powerline  connection.   A
              foreign device is any device not manufactured by Atheros.
