51 * Most of these functions have two separate blocks of code that are
52 * conditional on whether this is a station or an AP. This is used

54 * It's a choice (good, bad, indifferent?) to have the code in the same
55 * place so it's clear that the same primitive is implemented in both
56 * cases but has different behavior.
