i was wondering how we can improve the netmap memory allocator
to make use of 2M pages (through the page promotion trick).

in netmap, when we allocate packet buffers,
we issue requests for 4k blocks to contigmalloc(),
and i have no idea if there is a way to improve the
chance that the memory is mapped to 2M pages ?
