I just noticed one problem with this patch series. If I run the
following commands with Cardhu in its dock, and a USB Ethernet dongle
attached to the dock:

usb start 0
dhcp ${scriptaddr} boot.scr.uimg

... then everything works as expected; the file is downloaded.

However, if I run those same commands with Cardhu either undocked, or
docked but with no USB Ethernet dongle plugged into the dock, then the
dhcp command hangs the system hard; CTRL-C won't interrupt it for example.

Can you please fix this?
