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 #include <sys/cdefs.h> 80 __KERNEL_RCSID(0, "$NetBSD: if_aue.c,v 1.99.10.1 2007/05/22 14:57:36 itohy Exp $");
