usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.
