netfilter: nf_flow_table: hardware offload support
This patch adds the dataplane hardware offload to the flowtable
infrastructure. Three new flags represent the hardware state of this
flow:
* FLOW_OFFLOAD_HW: This flow entry resides in the hardware.
* FLOW_OFFLOAD_HW_DYING: This flow entry has been scheduled to be remove
from hardware. This might be triggered by either packet path (via TCP
RST/FIN packet) or via aging.
* FLOW_OFFLOAD_HW_DEAD: This flow entry has been already removed from
the hardware, the software garbage collector can remove it from the
software flowtable.
This patch supports for:
* IPv4 only.
* Aging via FLOW_CLS_STATS, no packet and byte counter synchronization
at this stage.
This patch also adds the action callback that specifies how to convert
the flow entry into the flow_rule object that is passed to the driver.
