6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@xxxxxxxxxx>
[ 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 ]
Fixes: 136a1b434bbb ("selftests: net: test vxlan pmtu exceptions with tcp")
