: The drivers are for different card/chipset models. Please see
:
: man if_rl
: man if_re

: Summary:
:
: rl -- RealTek 8129/8139 Fast Ethernet device driver
: re -- RealTek 8139C+/8169/816xS/811xS/8101E PCI/PCIe Ethernet
: adapter driver
The simpler driver was for a device that was fairly low end for its
time, so needed a lot of quirks and workarounds. The higher end
driver for re eliminates those quirks and uses more of the hardware
functions. There's some code shared between the two drivers.
