29 | * |
30 | * Most of these functions have two separate blocks of code that are |
31 | * conditional on whether this is a station or an AP. This is used |
32 | * to separate out the STA and AP responses to these management primitives. |
33 | * It's a choice (good, bad, indifferent?) to have the code in the same |
34 | * place so it's clear that the same primitive is implemented in both |
35 | * cases but has different behavior. |
