Summary

This is useful when dev.netmap.port_numa_affinity is set to 1. When
interfaces attach, they get a memory allocator that is copied from
nm_mem. Parameters in nm_mem can be set using sysctls, but this happens
after their values are copied.

To work around this, we can make it possible to set these memory
parameters as tunables.
