Source the ethtool library from the correct path and avoid the following
error:

The ethtool dump includes the lanes parameter only when the port is up.
Therefore, the ethtool_lanes.sh test waits for ports to come before testing
the lanes parameter.
In some cases, the test considers the port as up, but the lanes parameter
is not yet dumped although assumed to be, resulting in ethtool_lanes.sh
test failure.
To avoid that, ensure that the lanes parameter is indeed dumped by waiting
for it explicitly, before preforming the test cases.

Test that setting lanes parameter is working.
Set max speed and max lanes in the list of advertised link modes,
and then try to set max speed with the lanes below max lanes if exists
in the list.
And then, test that setting number of lanes larger than max lanes fails.
Do the above for both autoneg on and off.
$ ./ethtool_lanes.sh
TEST: 4 lanes is autonegotiated [ OK ]
TEST: Lanes number larger than max width is not set [ OK ]
TEST: Autoneg off, 4 lanes detected during force mode [ OK ]
TEST: Lanes number larger than max width is not set [ OK ]
