whether or not there is interface queue in hardware?

[lphao]

Hi, All

I read the hostap driver and linux kernel, I know the queue discipline(include red fifo etc.) existing at the top of driver. But I do not know whether or not there is interface queue between the driver and the MAC layer. If existing, does the queue implement in hardware? And what is the queue length?

thanks!
