>Description:
It appears that the Ethernet interface on the Au1100 chip
cannot receive at full speed - Whatever I try, I cannot
get it to operate at over 1.5Mbps. 
Sending through the Interface is fine, as it operates at 70-80Mbps.
Replacing the Switch/Ethernet Cable does not change the results.
>How-To-Repeat:
Use any means of TCP/IP transport on top of the Au1100
(Gateway, direct FTP transfer).

 This is almost certainly because you're missing a driver for your 
 board's PHY.

 Add the following line to your kernel config file and try again:

 acphy*  at mii? phy ?  #DAltima AC101 and AMD Am79c874 PHYs

 Cheers, Steve

 Well, This is what we call a "Quick Fix" over here! ;)

 Thanks, that did the trick.
 Could you please tell me where that is documented, 
 so I can avoid sending PR's needlessly? I've searched
 high and low and this, but to no avail...

 Thanks again, Gilad.

 Well in theory you should be able to look up the manual page for the 
 ethernet driver (aumac), which will usually reference the mii(4) 
 driver, which documents all the supported ethernet PHYs.

 Right now, Au1x00 ethernet is missing its manual page (which deserves a 
 PR in its own right)...

 If you're not sure whether something is a bug, you can always ask the 
 question on one of the mailing lists. In this case, port-evbmips and/or 
 netbsd-users would have been a good choice.

 Cheers, Steve
