IB/core: Introduce inner flow steering
For a tunneled packet which contains external and internal headers,
we refer to the external headers as "outer fields" and the internal
headers as "inner fields".
Example of a tunneled packet:
{ L2 | L3 | L4 | tunnel header | L2 | L3 | l4 | data }
| | | | | | |
{ outer fields }{ inner fields }
This patch introduces a new flag for flow steering rules
- IB_FLOW_SPEC_INNER - which specifies that the rule applies
to the inner fields, rather than to the outer fields of the packet.
