The chip uses the same RX filter scheme 50 * as the other ADMtek ethernet parts: one perfect filter entry for the 51 * the station address and a 64-bit multicast hash table. The chip supports 52 * both MII and HomePNA attachments. 53 * 54 * Since the maximum data transfer speed of USB is supposed to be 12Mbps, 55 * you're never really going to get 100Mbps speeds from this device. I 56 * think the idea is to allow the device to connect to 10 or 100Mbps 57 * networks, not necessarily to provide 100Mbps performance. Also, since 58 * the controller uses an external PHY chip, it's possible that board 59 * designers might simply choose a 10Mbps PHY. 60 * 61 * Registers are accessed using usbd_do_request(). Packet transfers are 62 * done using usbd_transfer() and friends. 63 */ 64 65 /* 66 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 67 */ 68 69 /* 70 * TODO: 71 * better error messages from rxstat 72 * split out if_auevar.h 73 * add thread to avoid register reads from interrupt context 74 * more error checks 75 * investigate short rx problem 76 * proper cleanup on errors 77 */ 78 79 #if defined(__NetBSD__) || defined(__OpenBSD__) 80 #include "opt_inet.h" 81 #include "opt_ns.h" 82 #include "bpfilter.h" 83 #include "rnd.h" 84 #endif /* defined(__NetBSD__) || defined(__OpenBSD__) */ 85 86 #include <sys/param.h> 87 #include <sys/systm.h> 88 #include <sys/sockio.h> 89 #include <sys/mbuf.h> 90 #include <sys/malloc.h> 91 #include <sys/kernel.h> 92 #include <sys/socket.h> 93 94 #if defined(__FreeBSD__) 95 96 #include <net/ethernet.h> 97 #include <machine/clock.h> /* for DELAY */ 98 #include <sys/bus.h> 99 /* "controller miibus0" required.
