libefx is a platform-independent library to implement drivers for Solarflare network adapters. It provides unified adapter family independent interface (if possible). Driver must provide efsys.h header which defines options (EFSYS_OPT_*) to be used and macros/functions to allocate memory, read/write DMA-mapped memory, read/write PCI BAR space, locks, barriers etc. efx.h and efx_types.h provide external interfaces intended to be used by drivers. Other header files are internal. From Solarflare Communications Inc. Signed-off-by: Andrew Rybchenko <arybchenko@solarflare.com> Reviewed-by: Ferruh Yigit <ferruh.yigit@intel.com>
