NAME

       mdioblock2 - Qualcomm Atheros Clause 45 MDIO Instruction Block Assembler

SYNOPSIS

       mdioblock2 [options] file [file] [...]  [>stdout]

       mdioblock2 [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 entered here using 802.3ae Clause 45 (or addr,
       data and mask)  format.   See  program  mdioblock  for  a  similar  program  that  accepts
       instructions in 802.3 Clause 22 (or phy, reg, 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 command 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 address, data and mask fields.  Fields are separated by whitespace.  Instructions
              are  terminated  with  semicolon.  Multiple instructions may appear on one line and
              one instruction may span  multiple  lines.   Script-style  comments  are  permitted
              between instructions but not between instruction fields.

       Operation message type for more information on MDIO Block format.

EXAMPLES

       The following command reads register instructions  from  text  file  mdio.txt  and  writes
       binary  file  mdio.bin.  In this example, the program acts as a filter, reading from stdin
       and writing to stdout.  Progress and error messages, if any, are written to stderr.

          # mdioblock2 < mdio.txt > mdio.bin

       The following command reads register instructions from files physetup.dat then flowctl.dat
       then misc.ins and writes one binary MDIO block to file mdio.bin.  The previous contents of
       file mdio.bin are overwritten.

          # mdioblock2 physetup.dat flowctl.dat misc.ins > mdio.bin

       An example register instruction file might look like this.  Instructions have  addr,  data
       and  mask  fields.   Instruction  fields  are separated by whitespace and instructions are
       terminate by a semicolon.  Multiple instructions can appear on one line or one instruction
       can span multiple lines.  Script-style comments are permitted between instructions but not
       between instruction fields.
