On the one hand it's used to indicate the length of the header managed by the hardware header cache, on the other hand we use it to indicate the head room for those devices that don't have a cache. Since your device wants both, it fails miserably. There are three ways out of this. You could have your own cache (I haven't looked at your headers so I don't know whether that makes sense), have no cache at all, or add a new field that gets added to hard_header_len for the purposes of calculating head room.
