GNIC help please

I'm currently running a Yellowfin GNIC (Packet Engines) card in my main 
server using a Serverworks chipset and with the card in a 64 bit PCI 
slot.  The NIC is linked into a D-link DES-3225G switch with a fiber 
gigabit module in slot 2.  It seems as though the card does not work at 
all unless I dump it into promiscuous mode with an ifconfig eth0 
promisc at startup.  If i try to ping out before dumping the card into 
promiscuous mode I get a destination unreachable reply.   With the 
ifconfig eth0 promisc command the NIC appears to function normally.

Could anyone please tell me if this is caused by the current driver 
included in kernel version 2.4.22 or if it may be an issue of me 
incorrectly configuring the switch.  I have it pretty much setup as a 
base switch configuration with nothing setup to VLAN, trunk, filter, 
etc.

Any suggestions would be greatly appreciated.

Thanks,

Sam
