Saying Y here will open some advanced configuration for TIPC.
Most users do not need to bother; if unsure, just say N.
-config TIPC_ZONES
- int "Maximum number of zones in a network"
- depends on TIPC_ADVANCED
- range 1 255
- default "3"
- help
- Specifies how many zones can be supported in a TIPC network.
- Can range from 1 to 255 zones; default is 3.
-
- Setting this to a smaller value saves some memory;
- setting it to a higher value allows for more zones.
-
