For the above options NETINFO is of the format: 'ip,hwaddr,mask,gw,dns1,dns2,domain'
Where
ip - the IP address of the network
hwaddr - the device hardware MAC address
mask - the netmask for the network
gw - the network gateway
dns1 - dns 1 host/ip address
dns2 - dns 2 host/ip address
domain - the network domain name
