Setup/Remove LAN port on static ip mode.
Support create/setup VLAN interface.
lan represents PHY port eth3. It means the native vlan.
LAN port will be added to a security zone, TRUSTED by default.

Usage:  $0 {set|del} {lan} [--ipaddr IPADDR] [--netmask NETMASK]
        $0 set {lan} --ipaddr IPADDR --netmask NETMASK [-S]
        --ipaddr IPADDR # static ipaddress
        --netmask NETMASK # format 255.255.255.0
        -S # don't restart service
Example:
    $0 set lan 192.168.254.254 255.255.255.0 # set lan port with static ip addresses
