└─>EtherExpress 16 support
In linux kernel since version 2.6.12  
If you have an EtherExpress16 network (Ethernet) card, say Y and
read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Note that the Intel
EtherExpress16 card used to be regarded as a very poor choice
because the driver was very unreliable. We now have a new driver
that should do better.

To compile this driver as a module, choose M here. The module
will be called eexpress.
