Software

openwifi's software lives in the openwifi repository. The kernel modules in driver/ sit between Linux mac80211 and the FPGA, and the on-board tools and scripts are in user_space/. The driver is a Linux platform driver built against the Analog Devices kernel, so ADI's kernel patches are a prerequisite for everything here.
