static ip on E312 not working

[GNU Radio, the Free & Open-Source Toolkit for Software Radio]

Hi all

i want to assign a static ip address to my E312, i have modify the
eth0.network file in /data/network, this is the content:

[Match]
Name=eth0
KernelCommandLine=!nfsroot

[Network]
Address=192.168.10.42
IPForward=ipv4

[DHCP]
UseHostname=true
UseDomains=true
ClientIdentifier=mac

But I rebooted the E312 and did not have the ip assigned, ¿does anyone know
why this is not happening?
