*****************************************************************
******** ***************
******** ttcp benchmark tests of dec2114x driver ***************
******** adapted from FreeBSD's if_dc.c for RTEMS ***************
******** by: Daron Chabot (12/15/03), ***************
******** <daron@nucleus.usask.ca> ***************
*****************************************************************
Test Equipment:
-----------------------
- Intel 450 MHz P3's
- RH Linux v7.3, 2.4.7-10 kernel, D-Link DFE-530TX (via-rhine)
- RTEMS rtems-ss-20030703, pc386 BSP, Linksys LNE100TX ( actually,
a cleverly disguised ADMtek Centaur, aka "Comet").
- the PCs were directly connected ( RJ-45 X-over cable ) on a class C
subnet (private)
NOTE:
-----------------------
- the following lines must be added to the BSP's "bsp.h" file, or
inserted into an application header (e.g. a "network_config.h" file, or
similar):
extern int rtems_dc_driver_attach(struct rtems_bsdnet_ifconfig *, int);
#define BSP_DEC_NETWORK_DRIVER_NAME "tl1" /* "tl" as in "tulip-clone" */
#define BSP_DEC_NETWORK_DRIVER_ATTACH rtems_dc_driver_attach
