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 ]

Currently different_speeds_get() is used only by ethtool.sh tests.
The function can be useful for another tests that check ethtool
configurations.
Move the function to ethtool_lib in order to allow other tests to use
it.

The lib files should not be defined as TEST_PROGS, or we will run them
in run_kselftest.sh.
Also remove ethtool_lib.sh exec permission.

Functions:
1. speeds_arr_get
The function returns an array of speed values from
/usr/include/linux/ethtool.h The array looks as follows:
[10baseT/Half] = 0,
[10baseT/Full] = 1,
...
2. ethtool_set:
params: cmd
The function runs ethtool by cmd (ethtool -s cmd) and checks if
there was an error in configuration
3. dev_speeds_get:
params: dev, with_mode (0 or 1), adver (0 or 1)
return value: Array of supported/Advertised link modes
with/without mode
* Example 1:
speeds_get swp1 0 0
return: 1000 10000 40000
* Example 2:
speeds_get swp1 1 1
return: 1000baseKX/Full 10000baseKR/Full 40000baseCR4/Full
4. common_speeds_get:
params: dev1, dev2, with_mode (0 or 1), adver (0 or 1)
return value: Array of common speeds of dev1 and dev2
* Example:
common_speeds_get swp1 swp2 0 0
return: 1000 10000
Assuming that swp1 supports 1000 10000 40000 and swp2 supports
1000 10000
