PCI version of Prism2.5/3 has undocumented DMA support for TX/RX data, but this seems to have some hardware bugs that prevent it from being used properly for TX. RX side could possibly be made to work reliably. Even though DMA support would be very useful for saving host CPU (from about 40% to 5-10% when operating at maximum throughput), it seems to be best to just remove this code finally. The implementation has always been commented out by default and has received very limited testing. The code may have already been broken number of times and I don't have much interested in trying to verify whether it works or not. Getting this out makes it easier to maintain the driver and allows some cleanups that have been partly postponed because of this experimental bus master/DMA code.
