   [PATCH] natsemi long cable fix
   
   This is a minor modification to the previous patch submission that does
   not assume the default contents of the DSPCFG register are zero.
   
   When used with Revision D of the DP83815, the "Recommended Registers
   Configuration" from page 78 of the DP83815 data sheet is not entirely
   compatible with the driver's "short cable patch".  When the DSPCFG
   register is written with the value suggested in the document, then
   do_cable_magic() can't read the DSP coefficient and determines that all
   cables attached to the DP83815D are 'short', regardless of actual
   length.  Short cables (< 30m) cause do_cable_magic to enable additional
   attenuation to reduce CRC and idle errors.  If the extra attenuation is
   unintentionally enabled for long cables (> 50m?), they will not operate
   properly.  The National Semiconductor driver, 'dp83815.c' from
   http://www.national.com/appinfo/networks/files/linux_2_4.tar.gz was used
   as a basis for this modification.
