From: Ido Schimmel <idosch@xxxxxxxxxx> commit 6bdf3d9765f4e0eebfd919e70acc65bce5daa9b9 upstream. The selftest relies on iproute2 changes present in version 6.3, but the test does not check for it, resulting in errors: # ./bridge_mdb_max.sh INFO: 802.1d tests TEST: cfg4: port: ngroups reporting [FAIL] Number of groups was null, now is null, but 5 expected TEST: ctl4: port: ngroups reporting [FAIL] Number of groups was null, now is null, but 5 expected TEST: cfg6: port: ngroups reporting [FAIL] Number of groups was null, now is null, but 5 expected [...] Fix by skipping the test if iproute2 is too old.
