[Neeraj Pal <neerajpal09@gmail.com>]

Sorry missed, Network info:

barebox@Sandbox:/ devinfo eth0
Parent: tap0
Parameters:
  ethaddr: 9e:47:e0:0b:cb:ab (type: MAC)
  gateway: 0.0.0.0 (type: ipv4)
  ipaddr: 0.0.0.0 (type: ipv4)
  linux.bootargs:  (type: string)
  linux.devname:  (type: string)
  mode: dhcp (type: enum) (values: "dhcp", "static", "disabled")
  netmask: 0.0.0.0 (type: ipv4)
  serverip:  (type: string)
barebox@Sandbox:/

After ifup -a

barebox@Sandbox:/ devinfo eth0
Parent: tap0
Parameters:
  ethaddr: 80:81:82:83:84:85 (type: MAC)
  gateway: 172.0.0.1 (type: ipv4)
  ipaddr: 172.0.0.2 (type: ipv4)
  linux.bootargs: ip=172.0.0.2:172.0.0.1:172.0.0.1:255.255.255.0:::
(type: string)
  linux.devname:  (type: string)
  mode: static (type: enum) (values: "dhcp", "static", "disabled")
  netmask: 255.255.255.0 (type: ipv4)
  serverip: 172.0.0.1 (type: string)
barebox@Sandbox:/ ping google.com
ERROR: dns: no nameserver specified in $net.nameserver
T T T T T ping failed: Connection timed out

It seems like it is not able to get the IP from DHCP so I am trying to
set up static, once.
