You've fallen into the D-Link marketing trap.  The DFE-530TX+ is
supported by the "rl" driver.  However, note the following comments from
the top of the driver (sys/dev/pci/if_rl.c):

 * The RealTek 8139 PCI NIC redefines the meaning of 'low end.' This is
 * probably the worst PCI ethernet controller ever made, with the possible
 * exception of the FEAST chip made by SMC. The 8139 supports bus-master
 * DMA, but it has a terrible interface that nullifies any performance
 * gains that bus-master DMA usually offers.

... and it goes on from there with further venting.
