Linville" Cc: linux-wireless@vger.kernel.org In-Reply-To: <1280260357.19686.13.camel@dcbw.foobar.com> References: <1280260357.19686.13.camel@dcbw.foobar.com> Content-Type: text/plain; charset="UTF-8" Date: Tue, 27 Jul 2010 13:03:46 -0700 Message-ID: <1280261026.19686.26.camel@dcbw.foobar.com> Mime-Version: 1.0 Sender: linux-wireless-owner@vger.kernel.org List-ID: Slightly different approach here since there are so many arguments to the firmware command. Just let the caller fill them in before pushing the command to the firmware.
