[net,0/2] fix wrong hds-thresh value setting

Message

A hds-thresh value is not set correctly if input value is 0.
The cause is that ethtool_ringparam_get_cfg(), which is a internal
function that returns ringparameters from both ->get_ringparam() and
dev->cfg can't return a correct hds-thresh value.

The first patch fixes ethtool_ringparam_get_cfg() to set hds-thresh
value correcltly.

The second patch adds random test for hds-thresh value.
So that we can test 0 value for a hds-thresh properly.

  net: ethtool: fix ethtool_ringparam_get_cfg() returns a hds_thresh
    value always as 0.
  selftests: drv-net: test random value for hds-thresh
