I use DEC-21140 based ether net card for 100BASE-FX.
And kernel configuration file is so ...

>Description:
The ethernet driver look like sending broken packet(So,
aliment error/CRC error). Becouse, other machine look and report
to me.
>How-To-Repeat:
Connect 100BASE-FX ethernet port and 100/10BASE switching hub,
Like this,
Machine-A Machine-B Machine-C
| | |
+---+---------------+----+ +----------------+
| 100BASE-FX dam hub | | 10BASE dam hub |
+----------+-------------+ +--------+-------+
| +--------------------------+ |
+-------| 100/10BASE switching hub |-----+
Segment-A +--------------------------+ Segment-B
1st, Machine-A send a large packet into machine-B.
Case of 50% ? packet is OK, But some packet look like broken
for Machine-B/Switching Hub.
>Fix:
This patch is stoping these BUG.
