In addition to comments in line, getRawFields, buildString, calcHashCode, and equals must be modified with consideration of element order.

All fields should be final as possible.
| private Dot11MeshIdElement meshId = null; | ||
| private List<Dot11VendorSpecificElement> vendorSpecificElements = new ArrayList<Dot11VendorSpecificElement>(); | ||

| private List<Dot11InformationElement> infoElementOrderedList = new LinkedList<Dot11InformationElement>(); |

infoElementOrderedList holds the same objects as the other fields such as meshId, which is a bad practice.
| int elemLen = elem.length(); | ||
| offset += elemLen; | ||
| length -= elemLen; | ||

I want the below code to be replaced with a packet factory like StaticIpV4OptionFactory for maintainability and enhanceability.
| * @return infoElementOrderedList | ||

| public List<Dot11InformationElement> getInformationElementOrderedList() { | ||
| return infoElementOrderedList; |

All fields must be immutable. So, here must make a defensive copy.

Please review these initial version of changes. Since I have to iterate inside the header elements constructor I am forced to take out the "final" declarations on information elements. I didn't want to do that though. Please take a look at this and let me know your thoughts on it. Also I have not worked on factory implementation yet. I will be working on that soon. Thanks
