If you want to submit a driver to the kernel, please post it to
netdev@vger.kernel.org.  Don't expect a driver to be just accepted; it
will go through a thorough review and after all the issues have been
resolved it will be accepted.

Wireless support under Linux is suffering from several problems:

 o some core require microcode to be loaded but the vendor does not
   give such permission.
 o lack of documentation, sometimes for paranoid or bogus legal reasons or
   "intellectual property" concerns.

At times it really seems vendors are working to maximize pain for the user ...

Well, for one thing because 802.11 is complex.  The Linux wireless support
has gone through several generations; some of the wireless work was for
one or the other reason never integrated in the kernel.org kernel.
