This device is 10Mbps half-duplex only, hence * there is no media selection logic. The MAC supports a 128 entry * multicast filter, though the exact size of the filter can depend * on the firmware. Curiously, while the software spec describes various * ethernet statistics counters, my sample adapter and firmware combination * claims not to support any statistics counters at all. * * Note that once we load the firmware in the device, we have to be * careful not to load it again: if you restart your computer but * leave the adapter attached to the USB controller, it may remain * powered on and retain its firmware. In this case, we don't need * to load the firmware a second time. * * Special thanks to Rob Furr for providing an ADS Technologies * adapter for development and testing. No monkeys were harmed during * the development of this driver. */ /* * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. */ /* * TODO: * only use kue_do_request for downloading firmware. * more DPRINTF * proper cleanup on errors */ #if defined(__NetBSD__) #include "opt_inet.h" #include "opt_ns.h" #include "bpfilter.h" #include "rnd.h" #elif defined(__OpenBSD__) #include "bpfilter.h" #endif #include #include #include #include #include #include #include #if defined(__FreeBSD__) #include #include /* for DELAY */ #include #elif defined(__NetBSD__) || defined(__OpenBSD__) #include #if NRND > 0 #include #endif #endif #include #if defined(__NetBSD__) || defined(__FreeBSD__) #include #endif #include #if defined(__NetBSD__) || defined(__OpenBSD__) #define BPF_MTAP(ifp, m) bpf_mtap((ifp)->if_bpf, (m)) #else #define BPF_MTAP(ifp, m) bpf_mtap((ifp), (m)) #endif #if defined(__FreeBSD__) || NBPFILTER > 0 #include #endif #if defined(__NetBSD__) #include #ifdef INET #include #include #endif #endif /* defined (__NetBSD__) */ #if defined(__OpenBSD__) #ifdef INET #include #include #include #include #include #endif #endif /* defined (__OpenBSD__) */ #if defined(__NetBSD__) || defined(__OpenBSD__) #ifdef NS #include #include #endif #endif /* defined(__NetBSD__) || defined(__OpenBSD__) */ #include #include #include #include #ifdef __FreeBSD__ #include #endif #include #include #ifdef KUE_DEBUG #define DPRINTF(x) if (kuedebug) logprintf x #define DPRINTFN(n,x) if (kuedebug >= (n)) logprintf x int kuedebug = 0;
