vnet: create L2 feature arc infrastructure
This commit adds two new nodes in the L2 datapath in input and output direction respectively. These nodes fork the traffic into three feature arcs: ip4, ip6 and nonip, which later join to continue the usual L2 processing. The vnet_l2_feature_enable_disable() function with the same signature as vnet_feature_enable_disable() takes care of enabling the L2 datapath feature bits as needed, when the features are enabled/disabled. Thus, L2 features may use the similar plumbing as the L3 features enjoy. Change-Id: I76877b3a92d794c492bff1622bb26acba05705b2 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
