Here are a few examples: - - "" /* use first device found supported by any driver in the - * libbsdport_driver_table[]. - */ - - "pcn2" /* use second device supported by the 'pcn' driver */ - - Notes: Counting instances begins with 1 (not 0). - Consult libbsdport/README for more information. - -KNOWN ISSUES: -- 'ignore_broadcast' and 'mtu' settings from - struct rtems_bsdnet_ifconfig are ignored. I haven't seen - many drivers that honour 'ignore_broadcast' and 'mtu' can be - set using a ioctl(). I'm trying to keep changes to BSD sources - minimal... -- ring sizes are restricted fixed to hardcoded size. -- Only the internal phy of the 973/975 chips are supported - and will allow SIOCGIFMEDIA/SIOCSIFMEDIA to work. I don't know - what happens with other chips or external phys. - Probably, the factory-default setup should work with autonegotiation - but the ioctls wont. YMMV. - -OTHER NOTES: -- you can use the (more generic) 'le' driver for the 79C971 - and upwards chips, too, but 'pcn' supposedly uses more advanced - features of these chips. - -TESTED WITH: - Technobox 10/100-TX Ethernet PMC (AMD Am79C973 chip) - -TESTED ON: - rtems-4.7 - powerpc/beatnik (motorola MVME5500 and MVME6100 VME boards) - i386/pc686 (concurrent technologies PP410 compact PCI) - -T.S, 200707 |
