| - | * Integrated with cfg80211 | + | The brcmfmac driver is based on the DHD driver, which is also released in AOSP under the name bcmdhd. Although similar the brcmfmac driver has been reworked significantly. In the figure below the layering of the brcmfmac is shown. It was made couple of years ago so it may not be accurate. |

| + | ==== Get Involved ==== | ||
| + | |||
| + | Maintaining a driver for a family of chipsets that is widespread and productized by multiple entities can be challenging. While having a good stock of devices it is by no means covering a fraction of the variants out in the wild. So we can always use help from people doing regression testing or co-maintaining the driver. The table below provides an overview of those involved and the role they play. | ||
