This device is 10Mbps half-duplex only, hence 51 * there is no media selection logic. The MAC supports a 128 entry 52 * multicast filter, though the exact size of the filter can depend 53 * on the firmware. Curiously, while the software spec describes various 54 * ethernet statistics counters, my sample adapter and firmware combination 55 * claims not to support any statistics counters at all. 56 * 57 * Note that once we load the firmware in the device, we have to be 58 * careful not to load it again: if you restart your computer but 59 * leave the adapter attached to the USB controller, it may remain 60 * powered on and retain its firmware. In this case, we don't need 61 * to load the firmware a second time. 62 * 63 * Special thanks to Rob Furr for providing an ADS Technologies 64 * adapter for development and testing. No monkeys were harmed during 65 * the development of this driver. 66 */ 67 68 /* 69 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 70 */ 71 72 #include <sys/cdefs.h> 73 __KERNEL_RCSID(0, "$NetBSD: if_kue.c,v 1.57 2006/10/12 01:31:59 christos Exp $");
