Subject: [PATCH net-next 30/38] selftests/net: convert test_vxlan_vnifiltering.sh to run it in unique namespace
Here is the test result after conversion.
]# ./test_vxlan_vnifiltering.sh
TEST: Create traditional vxlan device [ OK ]
TEST: Cannot create vnifilter device without external flag [ OK ]
TEST: Creating external vxlan device with vnifilter flag [ OK ]
...
TEST: VM connectivity over traditional vxlan (ipv6 default rdst) [ OK ]
TEST: VM connectivity over metadata nonfiltering vxlan (ipv4 default rdst) [ OK ]
Tests passed: 27
Tests failed: 0
