atheros lan driver

I do the network card driver, the main content is to design and improve the rate adjustment algorithm, With the new standard of 802.11 protocol cluster more and more, the rate is more and more high, modulation coding method is also more and more, generally speaking, the higher the rate is more likely to drop packets, the lower the rate is more stable, this is the overall situation, but not necessarily the law, so, only with a fixed rate to send is obv

network data is more complex than sending data. Because you need to assign a sk_buff in an atomic context and hand it over to the upper layer.Packet reception is implemented in two ways: Interrupt driver and polling. Most drivers are interrupt-driven. There are some high-throughput drivers that use polling methods.structintlength); 原子上下文中分配skbprintk_ratelimit() 限制printk的输出频率，在中断对应函数中降低输出To achieve a high-throughput network drive, the best way to redu

communicating.When the switch establishes the complete MAC address table, the data frame is forwarded by looking up the MAC address table to get the corresponding port, thus sending the data frame through a specific port. However, for broadcast data that enters from a port and no address entry is found in the Address table, the switch forwards the data frame from all ports except the access port. From this perspective, the devices connected by the switches are in the same broadcast domain, but
