Have you tried working with the upstream wireless developers? Perhaps
they can pluck the bits of wisdom from the OEM driver that will improve
the mainline driver performance.

The devs in question (from the mainline driver file
drivers/net/wireless/rtl818x/rtl8187_dev.c) are:

 * The driver was extended to the RTL8187B in 2008 by:
 *      Herton Ronaldo Krzesinski <herton at>
 *      Hin-Tak Leung <htl10 at>
 *      Larry Finger <Larry.Finger at>

Assuming, of course, that there are no licensing issues with the OEM
driver. I suggest that you also Cc linux-wireless at
