The part is in half duplex mode by default.
Unless you see "Media type forced to Full Duplex." the start-up messages the
duplex is negotiated using NWay
  http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html

You can verify that the chip is in half-duplex mode by running rtl8139-diag
  http://cesdis.gsfc.nasa.gov/linux/diag/index.html
and checking the contents of register Config1 at offset 0x52.
The Config1 register is shown as the second value in the output string
 
 The chip configuration is 0x%2.2x 0x%2.2x, %s mode.

It should read 0x20 rather than 0x60.

I've added a text string to the new version of rtl8139-diag.c to make this
easier to verify.
