poky/meta/recipes-connectivity/connman/connman-gnome/null_check_for_ipv4_config.patch

In networks that don't have a DHCP server configured, ipv4 address
allocation fails and the ipv4 structure doesn't get populated. When
the GUI is trying to read the ipv4_config.method field to see whether
it contains "dhcp" string, a segmentation fault is generated.

Ethernet manual configuration behavior remains unchanged after this fix.
