| 9 | Test Equipment: |
|---|
| 10 | ----------------------- |
|---|
| 11 | - Intel 450 MHz P3's |
|---|
| 12 | - RH Linux v7.3, 2.4.7-10 kernel, D-Link DFE-530TX (via-rhine) |
|---|
| 13 | - RTEMS rtems-ss-20030703, pc386 BSP, Linksys LNE100TX ( actually, |
|---|
| 14 | a cleverly disguised ADMtek Centaur, aka "Comet"). |
|---|
| 15 | - the PCs were directly connected ( RJ-45 X-over cable ) on a class C |
|---|
| 16 | subnet (private) |
|---|
| 17 | |
|---|
| 18 | NOTE: |
|---|
| 19 | ----------------------- |
|---|
| 20 | - the following lines must be added to the BSP's "bsp.h" file, or |
|---|
| 21 | inserted into an application header (e.g. a "network_config.h" file, or |
|---|
| 22 | similar): |
|---|
| 23 | |
|---|
| 24 | extern int rtems_dc_driver_attach(struct rtems_bsdnet_ifconfig *, int); |
|---|
| 25 | #define BSP_DEC_NETWORK_DRIVER_NAME "tl1" /* "tl" as in "tulip-clone" */ |
|---|
| 26 | #define BSP_DEC_NETWORK_DRIVER_ATTACH rtems_dc_driver_attach |
