Datasheet is available * from http://www.admtek.com.tw. * * Written by Bill Paul * Electrical Engineering Department * Columbia University, New York City */ /* * The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet * support: the control endpoint for reading/writing registers, burst * read endpoint for packet reception, burst write for packet transmission * and one for "interrupts." The chip uses the same RX filter scheme * as the other ADMtek ethernet parts: one perfect filter entry for the * the station address and a 64-bit multicast hash table. The chip supports * both MII and HomePNA attachments. * * Since the maximum data transfer speed of USB is supposed to be 12Mbps, * you're never really going to get 100Mbps speeds from this device. I * think the idea is to allow the device to connect to 10 or 100Mbps * networks, not necessarily to provide 100Mbps performance. Also, since * the controller uses an external PHY chip, it's possible that board * designers might simply choose a 10Mbps PHY. * * Registers are accessed using usbd_do_request(). Packet transfers are * done using usbd_transfer() and friends. */ /* * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. */ /* * TODO: * better error messages from rxstat * split out if_auevar.h * add thread to avoid register reads from interrupt context * more error checks * investigate short rx problem * 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 /* defined(__OpenBSD__) */ #include #include #include #include #include #include #include #include #include #include #if NRND > 0 #include #endif #include #if defined(__NetBSD__) #include #endif #include #include #define BPF_MTAP(ifp, m) bpf_mtap((ifp)->if_bpf, (m)) #if 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__) */ #ifdef NS #include #include #endif #include #include #include #include #include #include #include #ifdef AUE_DEBUG #define DPRINTF(x) if (auedebug) logprintf x #define DPRINTFN(n,x) if (auedebug >= (n)) logprintf x int auedebug = 0;
