>Description:
On TYAN Thunder 2462/Tiger 2460 bge-driven network card (3C996) passes only packets not over some small limit (typically 100-150 bytes). Moreover, this limit may be different after next power-on/off cycle. The same problem appears on the same hardware under Windows XP, but the problem disappears under W2K with 3c996 drivers from 3COM. Moreover, the problem under FreeBSD (and WinXP) disappears if it's booted after warm reboot after W2K, but reappears after full power-off/on.
Problem was first detected on FreeBSD 4.5
Problem appears if the card inserted into 64-bit slot, and into 32-bit slot also.
The problem is independent from link speed (10/100/1000).
The problem also exists with Altima AC1002-based Hardlink HA-64G card with bge driver patched to recognize this card.
Both cards works excellent with the same version of FreeBSD on i865-based Albatron board with Intel Celeron 1,7 G under heavy enough load.
>How-To-Repeat:
Just recreate this hardware config.
>Fix:
None known.
