Yes, completely compatible. I made sure max_p was initted with value
provided by tc (Plog based)

I also plan the TCA_RED_MAX_P support at configuration time with finer
granularity than 1/(2^Plog), so a new tc user can ask for precise
probability instead of current few discrete values. [ for non adaptative
RED of course, since max_p can change very fast otherwise :) ]
