+linux kernels above 4.2 ("Flower" classifier required).
+The kernel support can be checked with this command::

+ zcat /proc/config.gz | ( grep 'CLS_FLOWER=' || echo 'not supported' ) |
+ tee -a /dev/stderr | grep -q '=m' &&

+Supported items:

- vlan: vid, pcp, tpid, but not eid. (requires kernel 4.9)
