Hi all, 

I'm noticing considerable CPU usage of about 11% from io-pkt-v4-hc even when the system is idle. This is a MPC8548 @ 999
 Mhz. 

Starting io-pkt like this : 

# io-pkt-v4-hc -dmpc85xx mac=00E00C0000FD,pci=0,phy=0 -ptcpip

The hogs utility reports 11% usage for the io-pkt process. 

# hogs -n -%2
PID             NAME  MSEC  PIDS SYSTEM
1                     2645   86%    88%
1163283 io-pkt-v4-hc   358   11%    11%

Also observable when the Ethernet cable is off. 
Also reproducable on my system with io-pkt-v4. 

The IDE reports the same when qconn is connected. 

I could not observe that with io-net; its idle CPU usage was below measurable threshold.
