| 47 | * The functions in this file handle management requests sent from |
| 48 | * user mode. |
| 49 | * |
| 50 | * Most of these functions have two separate blocks of code that are |
| 51 | * conditional on whether this is a station or an AP. This is used |
| 52 | * to separate out the STA and AP responses to these management primitives. |
| 53 | * It's a choice (good, bad, indifferent?) to have the code in the same |
| 54 | * place so it's clear that the same primitive is implemented in both |
| 55 | * cases but has different behavior. |
