-/* Use PCI bus master to copy data to/from BAP (only available for
- * hostap_pci.o).
- *
- * Note! This is extremely experimental. PCI bus master is not supported by
- * Intersil and it seems to have some problems at least on TX path (see below).
- * The driver code for implementing bus master support is based on guessing
- * and experimenting suitable control bits and these might not be correct.
- * This code is included because using bus master makes a huge difference in
- * host CPU load (something like 40% host CPU usage to 5-10% when sending or
- * receiving at maximum throughput).
- *
- * Note2! Station firmware version 1.3.5 and primary firmware version 1.0.7
- * have some fixes for PCI corruption and these (or newer) versions are
- * recommended especially when using bus mastering.
- *
- * NOTE: PCI bus mastering code has not been updated for long time and it is
- * not likely to compile and it will _not_ work as is. Only enable this if you
- * are prepared to first fix the implementation..
