[Kernel-hackathon] [patch] TX running: probe, authentication, association and data frames

Attachments:
(text/plain) tx_running.patch (text/x-patch)

Author: Rodolfo Kohn
Date:
To: Mailing list for the VIA dongle driver hackathon
Subject: [Kernel-hackathon] [patch] TX running: probe, authentication, association and data frames

Configuration modified to set base type calling mac_set_bb_type (as CARDvSetBSSMode is called). Other configuration added.
vt6656_probe/start modified for executing initial configuration.
Tx modified to create tx descriptor and send probe, authentication,
association frames.Data frames also possible and ping has been tested.
Rx printk modified to print selected frames for debugging purposes.
Makefile modified to compile multiple source files.
New files added: vt6656_descriptor.[ch]
