doc: correct ip prefix token mapping table

[mjstapp]

Fix the table that shows the mapping between ip network cli tokens and the data struct that the cli handler will see. Optional network/subnet types appear as a pointer to an all-zeroes struct, not a NULL pointer.

[donaldsharp]

if this is true how do we tell the diff between 0.0.0.0/0 entered and no entry? This seems wrong.

if this is true how do we tell the diff between 0.0.0.0/0 entered and no entry? This seems wrong.

We get a prefixlen of zero (or a prefix type of zero) - it does (seem to) work, it's just not quite what was in the doc.
