help
|
Select this option if you want to use LCS networking on IBM System z.
|
This device driver supports FDDI (IEEE 802.7) and Ethernet.
|
To compile as a module, choose M. The module name is lcs.

Select this option if you want to use channel-to-channel
|
point-to-point networking on IBM System z.
|
This device driver supports real CTC coupling using ESCON.
|
It also supports virtual CTCs when running under VM.
|
This driver also supports channel-to-channel MPC SNA devices.
|
MPC is an SNA protocol device used by Communication Server for Linux.
|
To compile as a module, choose M. The module name is ctcm.
|
To compile into the kernel, choose Y.
|
If you do not need any channel-to-channel connection, choose N.

vehicle networking under VM or VIF. It enables a fast communication
|
link between VM guests. Using ifconfig a point-to-point connection
|
can be established to the Linux on IBM System z
