Hi John,
Here is the updated patch series,
I have dropped the compile warning patch because Johannes has
already send it before, the EIFS patch has been updated to use the
correct definition instead of hardcoding the value, and some
coding style fixes went into Iwo's patches.
Patches are still intended for 2.6.27
Ivo

In rt2x00 the value was ( SIFS + (8 * (IEEE80211_HEADER + ACK_SIZE)) ) which comes down to 314us while the legacy driver uses the value 364us This was caused because EIFS is: SIFS + DIFS + AckTime This patch will fix this by adding the DIFS by the above value, and creating a SHORT_EIFS define which uses the SHORT_DIFS.
