selftests: forwarding: ethtool: Move different_speeds_get() to ethtool_lib

2020-06-30T00:45:02Z

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.

selftests/net/forwarding: define libs as TEST_PROGS_EXTENDED

2020-03-25T19:01:18Z

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. Fixes: 81573b18f26d ("selftests/net/forwarding: add Makefile to install tests") Signed-off-by: Hangbin Liu Signed-off-by: David S. Miller

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 Signed-off-by: Amit Cohen Signed-off-by: Ido Schimmel Signed-off-by: David S.
