linux: network-basic: cover multiple subnets
On system uses multiple subnets, there is more then one gateway in route
table. For example:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.11.1 0.0.0.0 UG 100 0 0 enp0s25
default 192.168.0.1 0.0.0.0 UG 600 0 0 wlp3s0
This patch:
* Test the top default interface by default as it is the default interface
for all traffics.
* Obtain gateway by interface under test.
