[ Upstream commit bc0970d5ac1d1317e212bdf55533935ecb6ae95c ]
When running the pmtu.sh via the kselftest infra, accessing /dev/stdout gives unexpected results: # dd: failed to open '/dev/stdout': Device or resource busy # TEST: IPv4, bridged vxlan4: PMTU exceptions [FAIL]
Let dd use directly the standard output to fix the above: # TEST: IPv4, bridged vxlan4: PMTU exceptions - nexthop objects [ OK ]
