The chip uses the same RX filter scheme 51 * as the other ADMtek ethernet parts: one perfect filter entry for the 52 * the station address and a 64-bit multicast hash table. The chip supports 53 * both MII and HomePNA attachments. 54 * 55 * Since the maximum data transfer speed of USB is supposed to be 12Mbps, 56 * you're never really going to get 100Mbps speeds from this device. I 57 * think the idea is to allow the device to connect to 10 or 100Mbps 58 * networks, not necessarily to provide 100Mbps performance. Also, since 59 * the controller uses an external PHY chip, it's possible that board 60 * designers might simply choose a 10Mbps PHY. 61 * 62 * Registers are accessed using usbd_do_request(). Packet transfers are 63 * done using usbd_transfer() and friends. 64 */ 65 66 /* 67 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 68 */ 69 70 /* 71 * TODO: 72 * better error messages from rxstat 73 * split out if_auevar.h 74 * add thread to avoid register reads from interrupt context 75 * more error checks 76 * investigate short rx problem 77 * proper cleanup on errors 78 */ 79 80 #include <sys/cdefs.h> 81 __KERNEL_RCSID(0, "$NetBSD: if_aue.c,v 1.146 2019/01/22 03:42:28 msaitoh Exp $");
