en_xxx set the bits used in 802.3u (MII) configuration. Directly
setting the duplex and speed properties would be a subset of
functionality. (Because using the en_xxx bits, you can offer to support
more than a single configuration ... e.g. you could offer to support 100
FDX *and* 10 FDX.)
For more detail look at 802.3u.
