odp-util: Print bad action numbers in hexadecimal in format_odp_action(). Given that dpif.c clears action numbers to 0xcccc it can be much less mystifying to see that instead of 52428.

datapath: Replace "struct odp_action" by Netlink attributes. In the medium term, we plan to migrate the datapath to use Netlink as its communication channel. In the short term, we need to be able to have actions with 64-bit arguments but "struct odp_action" only has room for 48 bits. So this patch shifts to variable-length arguments using Netlink attributes, which starts in on the Netlink transition and makes 64-bit arguments possible at the same time.

flow: Separate "flow_t" from "struct odp_flow_key". The "struct odp_flow_key" used in the kernel datapath is conceptually separate from the "flow_t" used in userspace, but until now we have used the latter as a typedef for the former for convenience. This commit separates them. This makes it possible in upcoming commits to change them independently. This is cross-ported from the "wdp" branch, which has had it for months.

Expand tunnel IDs from 32 to 64 bits. We have a need to identify tunnels with keys longer than 32 bits. This commit adds basic datapath and OpenFlow support for such keys. It doesn't actually add any tunnel protocols that support 64-bit keys, so this is not very useful yet. The 'arg' member of struct odp_msg had to be expanded to 64-bits also, because it sometimes contains a tunnel ID. This member also contains the argument passed to ODPAT_CONTROLLER, so I expanded that action's argument to 64 bits also so that it can use the full width of the expanded 'arg'. Userspace doesn't take advantage of the new space though (it was only using 16 bits anyhow). This commit has been tested only to the extent that it doesn't disrupt basic Open vSwitch operation. I have not tested it with tunnel traffic. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com> Feature #3976.

tunneling: Add support for tunnel ID. Add a tun_id field which contains the ID of the encapsulating tunnel on which a packet was received (0 if not received on a tunnel). Also add an action which allows the tunnel ID to be set for outgoing packets. At this point there aren't any tunnel implementations so these fields don't have any effect. The matching is exposed to OpenFlow by overloading the high 32 bits of the cookie as the tunnel ID. ovs-ofctl is capable of turning on this special behavior using a new "tun-cookie" command but this command is intentially undocumented to avoid it being used without a full understanding of the consequences.

ofproto: Match VLAN PCP and rewrite ToS bits (OpenFlow 0.9) Starting in OpenFlow 0.9, it is possible to match on the VLAN PCP (priority) field and rewrite the IP ToS/DSCP bits. This check-in provides that support and bumps the wire protocol number to 0x98. NOTE: The wire changes come together over the set of OpenFlow 0.9 commits, so OVS will not be OpenFlow-compatible with any official release between this commit and the one that completes the set.
