bna: Tx and Rx Redesign

Browse Source 
Change details:
 - This patch contains the changes as a result of redesigning of Tx, Rx data
   path setup. In the old design, setting up Txqs, Rxqs were done in the driver.
   With the new design, most of the hardware setup steps for the Txq, Rxqs are
   moved to FW. Host driver issues commands to FW through the message queue to
   setup/teardown tx, rx data path. FW performs necessary steps and responds
   back to the driver with a status.
 - As a result of this redesign, the state machine implementation for Tx, Rx
   objects have changed significantly. Instead of doing the raw register access,
   these state machines mostly send a command to FW and wait for response and
   take the next action. In addition to tx, rx datapath setup, this patch also
   deals with rx filter configuration - such as unicast address, multicast
   address, vlan filter, promiscuous mode etc.
