problem with a DEC 21140 Fast Ethernet card



Hi,
 
We have a problem with our ethernet card. We are using a DEC PCI Fast Ethernet DECchip 21140 and Flux OSkit version 0.97.
 
We have set TULIP_PORT in ...linux/src/drivers/net/tulip.c equal to TULIP_100TP_PORT.
 
This is what "pingreply" prints during boot:
 
Probing devices...
tulip.c:v0.10 8/11/95 becker@cesdis.gsfc.nasa.gov
 +0.72 4/17/96 http://www.dsl.tutics.tut.ac.jp/~linux/tulip
 +0.72 12/15/96 mjacob@feral.com (2.0.72)
eth0: 21140 (DEC 21140 Tulip) at 0xd000, 00:40:05:a4:86:1f, IRQ 9
Current hardware tree:
  isa.isa   Industry Standard Architecture (ISA) Bus
    0xd000.tulip  DEC 21040 Ethernet Adaptor
1 Ethernet adaptor found:
    Tulip DEC 21040 Ethernet adaptor  00:40:05:a4:86:1f
eth0: enabling 100TX port.
bootp: Trying bootp with the tulip card (0:40:5:a4:86:1f)...
 
...then it makes no progress. The bootp server (10.1.1.21) does not receive any packet.
    We have tried all other values for TULIP_PORT. The enabled port changes accordingly, but the outcame is always the same.  
 
If tested on the same machine using FreeBSD, bootpd and bootptest show the following output:
