Eric Leblond 919377d4a5 af-packet: synchronize reading start 
This patch is updating af-packet to discard packets that have been
sent to a socket before all socket in a fanout group have been setup.
Without this, there is no way to assure that all packets for a single
flow will be treated by the same thread.

Tests have been done on a system with an ixgbe network card. When using
'cluster_flow' load balancing and disactivating receive hash on the iface:
 ethtool -K IFACE rxhash off
then suricata is behaving as expected and all packets for a single flow
are treated by the same thread.

For some unknown reason, this is not the case when using cluster_cpu. It
seems that in that case the load balancing is not perfect on the card side.

The rxhash offloading has a direct impact on the cluster_flow load balancing
because load balancing is done by using a generic hash key attached to
each skb. This hash can be computed by the network card or can be
computed by the kernel. In the xase of a ixgbe network card, it seems there
is some issue with the hash key for TCP. This explains why it is necessary to
remove the rxhash offloading to have a correct behavior. This could also
explain why cluster_cpu is currently failing because the card is using the
same hash key computation to do the RSS queues load balancing.
