Select this option if you want to use LCS networking on IBM System z.
This device driver supports Token Ring (IEEE 802.5),
FDDI (IEEE 802.7) and Ethernet.
This device driver supports FDDI (IEEE 802.7) and Ethernet.
To compile as a module, choose M. The module name is lcs.
If you do not know what it is, it's safe to choose Y.
