Description (partial)

Access point goes into a boot loop.  The switch shows the link as up, but no CDP information.
The AP console shows messages similar to the following:

[*02/23/2018 18:40:50.3857] waiting for POE negotiation to complete
[*02/23/2018 18:40:52.9034] SYS-COND: AP is in critical condition

[*02/23/2018 18:41:10.6537] aptrace_register_sysproc_fn: duplicate registeration for 'wired'

- switch port speed is configured for 100Mbps (or, in some cases, a port configured for 1Gbps may come up in 100Mbps due to cabling)
- AP2802 or 3802 (problem does not affect IOS APs or 1800 series)
