Subject: [PATCH] [PATCH] USB: usb-net: new device ID passed through module
parameter
adds new module parameter "devid" that points to a string with format
"device_name:vendor_id:device_id:flags". if provided at module load
time, this string is being parsed and a new entry is created in
usb_dev_id[] and pegasus_ids[] so the new device can later be recognized
by the probe routine. this might be helpful for someone who don't
know/wish to build new module/kernel, but want to use his new usb-to-eth
device that is not yet listed in pegasus.h
