Hmm, may be interesting some day.

Having thought about it a bit more, a layout similar to the one
proposed by you may make sense.

Hey again,
Code placement:
Queue Manager & NPE code => arch/arm/mach-ixp4xx
WAN driver code => drivers/net/wan
Eth code => drivers/net/arm
Why would you want such placement?
Potential problems: header files would have to be moved to
include/asm-arm = heade
