ovs_flow_extract - extracts a flow key from an Ethernet frame. : sk_buff that contains the frame, with skb->data pointing to the Ethernet header : port number on which was received. : output flow key : length of output flow key
The caller must ensure that skb->len >= ETH_HLEN.
Returns 0 if successful, otherwise a negative errno value.
Initializes header pointers as follows:
- skb->network_header: just past the Ethernet header, or just past the VLAN header, to the first byte of the Ethernet payload.
- skb->transport_header: If key->dl_type is ETH_P_IP or ETH_P_IPV6 on output, then just past the IP header, if one is present and of a correct length, otherwise the same as skb->network_header. For other key->dl_type values it is left untouched.

ovs_flow_from_nlattrs - parses Netlink attributes into a flow key. : receives the extracted flow key. : number of bytes used in . : Netlink attribute holding nested OVS_KEY_ATTR_* Netlink attribute sequence.

ovs_flow_metadata_from_nlattrs - parses Netlink attributes into a flow key. : receives the extracted input port. : Netlink attribute holding nested OVS_KEY_ATTR_* Netlink attribute sequence.
This parses a series of Netlink attributes that form a flow key, which must take the same form accepted by flow_from_nlattrs(), but only enough of it to get the metadata, that is, the parts of the flow key that cannot be extracted from the packet itself.
