ps3 gelic network driver doesn't restart properly

Hi,

there seems to be a problem with the ps3 gelic network driver. The first
time the interface is configured (in my test case over dhcp) the
interface is set up just fine. However after a

ifconfig down eth0
ifconfig up eth0

the interface  isn't set up right and a following

ifconfig down eth0

is hanging in D status. For further investigation I'll attach some logs
where a network restart has been triggered. I reproduced this with a
2.6.22 kernel and the 2.6.23-rc3 kernel from Geoff's git tree.
