The iwl3945 and iwl4965 devices share some common structure, but with a lot of difference split all over. Currently the two drivers share a lot of headers and use ugly preprocessor magic to manage the difference. This patch keeps two entirely separate copies of the headers to get rid of these hacks an ease future development.
