[vox-tech] DFE-530TX+, cheap ethernet



  This is not an endorsement of either Fry's or D-Link... I am not 
recommending anyone patronize or boycott either business.


  So a deal going on at Fry's... D-Link DFE-530TX+ 10/100 PCI Adapters 
for $5 each.  The price tag shows $15, but the register rings up $5, 
I've tried arguing with them twice before about things like this and 
its not worth the hassle because they don't adjust the price (lower on 
the tags or higher on the receipt :).


  There are two different boxes available a mostly white box and a
mostly blue box.  The pictures are slightly different, and the chip
right next to the ethernet jack is a little different, but everything
else on the boards look the same.

  Thinking I was going to pay $30, I only bought two.  One of each box 
(obviously).

I see three software drivers available for this card:
========
1 - downloadable from the D-Link web site
  ftp://ftp.dlink.com/NIC/dfe530tx+/Driver/dfe530TX+_linux_driver_051801.zip
  (D-Link's sites are behind a antiquated firewall so you will have
   to disable tcp_ecn if you want to connect to them).
2 - from Donald Becker's web site
  http://www.scyld.com/network/rtl8139.html
3 - in the 2.4.18 kernel tree
  /usr/src/linux/drivers/net/8139too.c

1:
  Probably works in a 2.2 kernel, it does not compile on 2.4.18.

2:
  Donald's Driver requires a number of auxiliary files 
  (pci-scan.[ch] kernel_compat.h) which are also available from his
  site.  His driver is version v1.17 last updated 2002-01-28.
    His directions for compiling these drivers do not produce loadable
  modules on a 2.4.18 kernel.  I can see dozens of other people having
  this problem on the bug lists he maintains for this driver ... 
  but I'm still trying things.

    He has a section that talks about 'How this driver differs from the 
  2.4 "8139too.c"', I'm not sure this document still applies:
  - I can plainly see the copyright text has been corrected.
  - The mmio read-after-write that he complains about I can't actually
    see happening in the driver for regular use there is a debug switch
    that will turn that behavior on, but it's off by default.

    One opinion I did make is that the kernel 8139too.c driver appears to
  be more readable source code, due to formating and comment blocks.  
  I'm not equipt to comment on the quality of either code base.


3:

  The kernel driver compiles and works.  Benchmarks to follow.


  So if you are at Fry's and looking for some inexpensive cards you
may want to take some to the register and if they ring up at $5 buy a 
dozen.
