Hint: Instead of adding numgen_map_expr, what you could do is to reuse
the existing parser. Look:
# nft add rule x y numgen inc mod 2 @x
Error: Set 'x' does not exist
add rule x y numgen inc mod 2 @x
^^
So the parser supports this, and the tree looks like this:
relational
/ \
/ \
numgen map
expr
> + {
> + $$ = numgen_expr_alloc(&@$, $2, $4, $5, $6);
Instead of passing the map as an argument to numgen_expr_alloc().
The idea then from netlink_linearize is to do the appropriate handling
for this tree to generate one single instruction.
