* 802.11 error codes: The AP can give us a status code explaining why
* authentication failed, or a reason code explaining why we were
* deauthenticated/disassociated. These codes range from 0-63 (the
* field is 16 bits wide, but only up to 45 or so are defined yet; we
* allow up to 63 for extensibility). This is encoded into an error
* code as such:
*
* status & 0x1f goes here --vv--
* Status code 0-31: ECONNREFUSED | EUNIQ_(status & 0x1f) (0e1a6038)
* Status code 32-63: EHOSTUNREACH | EUNIQ_(status & 0x1f) (171a6011)
* Reason code 0-31: ECONNRESET | EUNIQ_(reason & 0x1f) (0f1a6039)
* Reason code 32-63: ENETRESET | EUNIQ_(reason & 0x1f) (271a6001)
*
* The POSIX error codes more or less convey the appropriate message
* (status codes occur when we can't associate at all, reason codes
* when we lose association unexpectedly) and let us extract the
* complete 802.11 error code from the rc value.
