[PATCH 5.2 028/162] selftests: forwarding: gre_multipath: Enable IPv4 forwarding

[Greg Kroah-Hartman]

[ Upstream commit efa7b79f675da0efafe3f32ba0d6efe916cf4867 ]

The test did not enable IPv4 forwarding during its setup phase, which
causes the test to fail on machines where IPv4 forwarding is disabled.
