Enabling Ethernet Port for Browsing
Kernel
Ethernet support is already built into the default Kernel
configuration provided by Texas Instruments. To double check if
ethernet is set in the kernel configuration, look in the .config file
in the Kernel root directory and check that the following is set to "y":

• CONFIG_INET
• IP_PNP
• CONFIG_IP_PNP_DHCP
• CONFIG_NET_ETHERNET
• CONFIG_MII
• CONFIG_SMC911X

If Ethernet and networking configurations are not enabled properly,
then use the menu config to enable it. To enter menu config, type "make
menuconfig" in the Kernel root directory. Follow the following to enable

• Networking supportàNetworking optionsà
     
  • TCP/IP networking
  • IP: kernel level autoconfiguration
  • IP: DHCP support
  
     
• Device DriversàNetwork device supportàEthernet (10 or 100Mbit)à
     
  • Generic Media Independent Interface device support
  • SMSC LAN9115678
    ?
    support
  
     

U-Boot Bootargs
Once you have a proper kernel image, ethernet and TCP/IP should be
operational. To get a valid DHCP add "ip=dhcp" to the u-boot bootargs
environment variable, i.e. setenv  bootargs 'console=ttyS3,115200n8 root=/dev/mmcblk0p2 rw rootdelay=1 mem=256M  ip=dhcp  init=/init'
With the ip variable set in the bootargs, the kernel will use DHCP
during boot-up to grab IP address from the DHCP server. Once this
variable is set, the kernel will block until it detects a valid
connection.
Android Properties
To
get the Android browser to resolve address names, set the DNS server
property. In either the ADB or COM shell, give the following command: “setprop net.dns1 xxx.xxx.xxx.xxx” where xxx.xxx.xxx.xxx is the IP address to  your DNS server.
Note: If you are behind a proxy, then at the time this article was
written we have NOT found a method to set the proxy server for the
Android browser to use. We have tried using "setprop
net.eth0.http-proxy hostname:port" and "setprop net.gprs.http-proxy
hostname:port", but neither could get us through the proxy. Also, the
option of adding an entry of (99,'http_proxy','hostname:port") to the
'system' and 'secure' tables in
the /data/data/com.android.providers.settings/databases/settings.db
database has also been tried, but failed.
