Hi John, Here are 3 patches for rt2x00 intended for the 2.6.27 kernel. It finally fixes the ifdown & ifup breakage in rt61pci, as well as a BUG_ON() which was triggered during such an ifdown & ifup cycle. Ivo

Although most rt2x00 debugfs files don't contain information which could compromise network security, it is better to set the access permissions to root only. This will be required when HW crypto is implemented, because it could be possible to read the HW key from the registers.

The if-statement to determine the new TX/RX antenna configuration was incomplete. It lacks the general else-clause when the antenna wasn't changed. This is a correct event, since it can occur when only one of the antenna's has been changed or when the new configuration is being forced (like when the interface has just been added).

After the hardware has indicated the firmware upload has completed and the device is ready, we should wait another millisecond to make sure the device is really ready to continue. Without this timout, bringing the interface down and up again will fail due to incorrect register initialization.
