This patchset adds support for the collection and propagating of per-rate, per-station rx statistics when subscribed by userspace applications.
These statistics can be useful in understanding the quality of communication with our peers and in evaluating how different peers are communicating in different MCS/BW/NSS during different time periods and environment. This patchset is based on the below implementation by Johannes, to publish the stats when user space clients have subscribed and dump and clear when a certain threshold of stats is reached. http://thread.gmane.org/gmane.linux.kernel.wireless.general/133172 Few changes are made to the above implementation, 1. Dynamic memory allocation of stats data structures 2. Rate is encoded and used as key of hash table for scalablility.
