This is caused by the fix for bug 1890136, where this test case is reporting false-negative results.

With that bug fixed, it's reflecting the real failure in this sub category.

And this specific failure can be found in 5.4.0-45 s390x as well, so this is not a regression.

[Kleber Sacilotto de Souza (kleber-souza)]

This is clearly an endianness issue. I'll investigate whether the testcase needs to adapt to it or the sysfs interface of the netdevsim device needs to follow a pattern no matter what the system's endianness.
