"Members of the OpenWrt team have been in contact with Linksys for a while, discussing collaboration on device support in OpenWrt. There had been no technical collaboration on device support until Belkin engineers posted a few incomplete patches in early April. These patches are currently being cleaned up, as they do not meet our quality standards.
The most important part that is still missing is a usable driver for the Marvell 802.11ac wireless chipset. Belkin is working on fixing this, but they have not given us an estimation on when such a driver will be provided.
The default firmware for this device seems to be using a proprietary driver provided by Marvell, which uses non-standard APIs for configuration. We don't know if Marvell will open source this driver, or will work on an alternative Linux driver. We believe that both approaches require a considerable amount of effort and time."
