The main changes are as follows: 1. Support for the PHY mode switch implemented for some models. 2. Implementation of new routines for the dual-MAC devices. 3. Implement a mechanism for reaching the private data storage of the other unit in a dual-MAC device. 4. Impplementation of RX aggregation. 5. Storage of beacon statistics for roaming. 6. The RX routine has been rewritten to reduce the number of O(1) buffers.
