            Bug ID: 60662
           Summary: MosChip MCS7830 Ethernet adapter no longer working

This bug may or may not be related to
bug #60521 usbnet changes in 3.10 stop use of sierra_net devices
Since both resolutions are different, I decided to create a new bug.

With kernels 3.10.4 and 3.10.0, my Delock USB Ethernet adapter (using a MosChip
device) hardly survives the DHCP phase, then quickly becomes unresponsive. 
Sometimes even during DHCP.

Things went back to normal after reverting commit

4be74c130d1c5c03bccef0ab8d7a6bb71c7de53a usbnet: mcs7830: apply
usbnet_link_change

I haven't digged any further so far.
