Rdamicro's rdawfmac FullMAC driver for the RDA5995 802.11b/g/n chip
(USB 1e04:8888, or SDIO). The firmware and power_config.txt are compiled
into the module from the rdawlan/*.bin.hex arrays (WLAND_DOWNLOAD_FIRMWARE_FROM_HEX
in rdawlan/wland_defs.h); nothing is read from the filesystem. The RF test-mode
images are left out.
