3COM cards

configname: CONFIG_NET_VENDOR_3COM

Linux Kernel Configuration
└─>Networking support
└─>Ethernet (10 or 100Mbit)
└─>3COM cards
In linux kernel since version 2.6.12  
If you have a network (Ethernet) card belonging to this class, say Y
and read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.

Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about 3COM cards. If you say Y, you will be asked for
your specific card in the following questions.
