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

You can verify that the chip is in half-duplex mode by running rtl8139-diag
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.
