+ Unicore processors can not fetch/store information which is not

+ fetch/store instructions will be emulated in software if you say
+ here, which has a severe performance impact. This is necessary for
+ correct operation of some network protocols. With an IP-only
+ configuration it is safe to say N, otherwise say Y.
