The WLAN software package contains the WLAN host driver(bcmdhd) runs on the host, a WLAN binary

firmware for WLAN module.

The WLAN driver passes IEEE 802.3 packets, and the necessary control packets, back and forth over

packets on a separate logical control channel and to add __ packet information to the data channel.

The advantage of using the concept is that the device firmware is executed externally from a host device,

which means the host device does
