ti8168 原始文件系统进去后没有网络eth0接口，为了有该接口需要配置/etc/network/interfaces 文件
具体配置如下(红色要配置)
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
#
# Example of an unencrypted (no WEP or WPA) wireless connection
# that connects to any available access point:
#
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
#
#
# Same as above but locked to a specific access point:
#
#iface wlan0 inet dhcp
# wireless_mode managed
# wireless-essid some-essid
#
# A WEP encrypted connection locked to a specific access point:
#
#iface wlan0 inet dhcp
# wireless-essid some-essid
# wireless-key s:My-PlainText-Password
# wireless-mode managed
#
# A WPA1 or WPA2 encrypted connection locked to a specific access point.
# This is the best option for non-roaming, single-network usage.
# Note that your card may require a firmware update to use WPA.
# Some distributions install a temporary volatile firmware update on ifup.
#
#iface wlan0 inet dhcp
# wpa-essid some-essid
# wpa-psk My-PlainText-Password
#
# A WPA1 or WPA2 encrypted connection using an external configuration file
# for wpa-supplicant. This is the way to go if you need to configure multiple
# networks with different keys and / or WPA settings and roaming support.
#
# iface wlan0 inet dhcp
# wpa-conf /etc/wpa_supplicant.conf
# wpa-driver hostap
iface atml0 inet dhcp
# Wired or wireless interfaces
