Module: r819xusb_cmdpkt.c (RTL8190 TX/RX command packet handler Source C File)
|
|
|
|
Note: The module is responsible for handling TX and RX command packet.
|
|
1. TX : Send set and query configuration command packet.
|
|
2. RX : Receive tx feedback, beacon state, query configuration
|
|
command packet.
