Subject: weird current behaviour...

Network:

	machine-A  en0 ------------ en0 machine-B
	 de0  fxp0
          |	\
	  |	 ----------------- de0 machine-C
          |
         hub ----- machine-D
	  | 
          |
	 ed0
	machine-E


These two cases:

1. ping from A to E
2. ping from A to D

I see the round-trip time flutter from 9msec to 70 msec...

Every other path the round-trip time is OK, including confusingly 
enough:

	from E to A
	from D to A
	from B&C to E
	from B&C to D

What gives ?

Is the if_de driver broken somehow ?  

Does anybody else see this ?

Machine-A is a PR440FX motherboard with 2xP6/233 running current-SMP.

I have tried two different de0 cards and both does this.
