| H A D | nf_flowtable.rst | 4 Netfilter's flowtable infrastructure
7 This documentation describes the Netfilter flowtable infrastructure which allows
8 you to define a fastpath through the flowtable datapath. This infrastructure
9 also provides hardware offload support. The flowtable supports for the layer 3
17 flowtable through your ruleset. The flowtable infrastructure provides a rule
18 action that allows you to specify when to add a flow to the flowtable.
20 A packet that finds a matching entry in the flowtable (ie. flowtable hit) is
24 there is no matching entry in the flowtable (ie. flowtable miss), the packet
27 The flowtable uses a resizable hashtable. Lookups are based on the following
32 The 'flow add' action allows you to populate the flowtable, the user selectively
