Message-ID: <20070613022143.GD4187@tuxdriver.com>

From: "John W. Linville" <linville@...driver.com>

Subject: Please pull 'rtl8187' branch of wireless-2.6
Jeff,
This is the second round for the new mac80211-based rtl8187 driver.
Michael and Ivo responded to many of the original review comments,
and I have added a couple of patches to minimally address some
remaining issues. Please look at the comments I added to the header
blocks to see if that is satisfactory regarding explanation of the
magic values in the driver.
This is a new driver, so obviously it would be targeted towards 2.6.23.
John
