The addtron site has a module there for download. Its precompiled for
2.4.2 (or so it would seem based on the makefile), and some instructions
for getting it working. A few nice features such as Transmit and Receive
queue sizing, as well as info for 'jumbo frames' up to 4000 bytes. However,
thats if you get it working. Anyone using this? Anyone tried to compile the
module? (I got a few compilation errors relating to asm header files in the

get these yet? success?
