NAME

       int6kmdio - Qualcomm Atheros 16-bit MDIO Register Editor

SYNOPSIS

       int6kmdio [options] [device] [device] [...]

DESCRIPTION

       Read or write the generic MDIO registers on an Atheros powerline device using the Qualcomm
       Atheros VS_MDIO_COMMAND vendor-specific management message.  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 802.3 Clause 22 (phy, reg, data and mask)
       format.  See program int6kmdio2 for a similar program to write instructions using  802.3ae
       Clause 45 (address, data and mask) format.

       This  program  is  deprecated  and  may be removed in later toolkit releases.  Use program
       plcmdio16 instead.

OPTIONS

       -d data
              A 16-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.

       -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.

       -p address
              The  5-bit  PHY  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".

       -q     Suppresses status messages on stderr.

       -r register
              The 5-bit register address.  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".   Some  devices  may  not  support  all
              possible addresses.

       -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.
