    mdioblock(1)                                 Qualcomm Atheros Open Powerline Toolkit                                mdioblock(1)

    NAME
           mdioblock - Qualcomm Atheros Clause 22 MDIO Instruction Block Assembler

    SYNOPSIS
           mdioblock [options] file [file] [...]  [>stdout]

           mdioblock [options] [<stdin] [>stdout]

    DESCRIPTION
           Assemble  an  Atheros MDIO instruction block from hexadecimal register instructions.  MDIO instruction blocks are written
           to Atheros powerline devices as modules using the VS_MOD_OP message type.  Alternately, program int6kmod can be used.

           Atheros MDIO modules consists of a 16-bit header followed by one or more MDIO communication frames  with  register  masks
           and  padded  to  the nearest multiple of 32-bits for download purposes.  MDIO instructions are specified here using 802.3
           Clause 22 (or phy, reg, data and mask) format.  See program mdioblock2 for a similar program that accepts instructions in
           802.3ae Clause 45 (or address, data and mask) format.

           This  program  is  part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page for an overview and installation
           instructions.

    OPTIONS
           -q     Quiet mode.  Suppresses error messages caused by instruction syntax errors.

           -v     Verbose mode.  Prints instructions on stderr as they are processed.

           -?,--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 com‐
                  mand line except help information.  Use this option when sending screen dumps to Atheros technical staff.

    ARGUMENTS
           file   A text files contining one or more generic MDIO register intructions consisting of  a  phy,  reg,  data  and  mask
                  fields.  Fields are seperated by whitespace and instructions are terminated with semicolon.  Multiple instructions
                  may appear on a single line or a single instruction can span multiple lines.  Script-style comments are  permitted
                  between instructions but not between fields.

    REFERENCES
           See the Qualcomm Atheros AR7x00 Firmware Technical Reference Manual section on the Module Operation message type for more
           information on MDIO Block format.

    DISCLAIMER
           Atheros HomePlug AV Vendor Specific Management Message structure and content is proprietary to Qualcomm Atheros, Ocala FL
           USA.   Consequently,  public  information  may  not  be available.  Qualcomm Atheros reserves the right to modify message
           structure and content in future firmware releases without any obligation to notify or compensate users of this program.

    EXAMPLES
           The following command reads register instructions from file mdio.txt and writes them as an MDIO  program  block  to  file
           mdio.bin.  In this example, the program acts as a filter.

              # mdioblock < mdio.txt > mdio.bin

           The following command reads register instructions from files physetup.dat, flowctl.dat and misc.ins and write them all as
           one MDIO block to file mdio.bin.  The previous contents of file mdio.bin is overwritten.

              # mdioblock physetup.dat flowctl.dat misc.ins > mdio.bin

           An example register instruction file might look like this.  The first two lines consist  of  one  instruction  each.   An
           instruction  has phy, reg, data and mask fields.  Instruction fields are separated by whitespace.  Instructions are sepa‐
           rated by a semicolon.  Multiple instruction may appear on one line and one instruction can span multiple lines.   Script-
           style comments are permitted between instructions but not between instruction fields.

              18 00 0000 FFFF;
              10 16 003F FFFF;

              # multiple instructions on one line;

              10 17 7E3F FFFF; 18 00 0000 FFFF;

              # one instruction on multiple lines;

              10

              02

              0700

              FFFF;

              10 03 0000 FFFF;
              18 00 0000 FFFF;
              14 00 007D FFFF;
              14 01 0000 FFFF;

           A  16-bit  hexdump  of  the MDIO block will look like this on little-endian hosts.  The block consists of a 16-bit header
           followed by a variable number of 16-bit triplets.  The header indicates the number of triplets that follow.  Each triplet
           specifies  a 16-bit operation, a 16-bit data value and a 16-bit data mask.  The application of these fields is beyond the
           scope of this man page.  Consult the IEEE standards for more information.

              # hexdump mdio.bin
              0000000 0241 8185 0000 ffff ad05 003f ffff af05
              0000010 7e3f ffff 8185 0000 ffff 8505 0700 ffff
              0000020 8705 0000 ffff 8185 0000 ffff 8145 007d
              0000030 ffff 8345 0000 ffff

           An 8-bit dump of the MDIO block will look like this on all hosts since the MDIO block is always  distributed  in  little-
           endian format.
