[PATCH] r8152: add vendor/device ID for CoreChips SR9900

[PATCH] r8152: add vendor/device ID for CoreChips SR9900

[zjzhao]

From: zjzhao-eda <zjzhao@edatec.cn>

The CoreChips SR9900 (0x0fe6:0x9900) is a USB 2.0 10/100
Ethernet adapter. Testing shows it works correctly with the
r8152 driver, reaching wire speed (94 Mbps) with zero packet
loss on both TCP and UDP.

Tested on Raspberry Pi, including hotplug and extended data
transfer.

AFAIK the DCO must contain a full name and not just an alias

Also please indicate the target tree for your patch in the subject (eg. net-next). For furher details, have a look at the netdev FAQ.

Do you know how they differ to the other CoreChip devices (eg.
drivers/net/usb/sr9800.c and others)?

Instead of hardcoded 0x0fe6, please add a proper VENDOR_ID define in 
include/linux/usb/r8152.h
