How rude. Can we please get that message killed in both 2.6.21 and
2.6.20.x?

With the previous TSC having that strange value (020000000000), there must be some sort of driver
and/or AP error. With the possible exception of the situation where the "previous" and "received"
TSC are the same indicating a retransmit, I feel such messages are of value and do not support
killing them.
