selftests: drv-net: Check the features set by set_ethtool_feat()

Read back the features after running ethtool -K to check if they were
actually applied. The drivers might refuse to set a feature silently and
the test could run with a different configuration than the requested one.

Add a 'check' parameter to skip this, as the GRO "hw" mode handles the
case where HW GRO is cleared by the driver.
