This series improves the peak sustained flow setup rate by about
29% overall (4% in one commit, 24% on top of that in another),
as measured with "ovs-benchmark rate" on my pair of test machines.
The first two commits are bug fixes.
Ben Pfaff (13):
ofproto-dpif: Properly re-translate uninstallable facets in
rule_execute().
ofproto-dpif: Revalidate tagged packets, too, in
facet_lookup_valid().
netlink: New functions for putting attributes at the beginning of a
buffer.
netlink: New macros for the sizes of Netlink attributes.
ofproto-dpif: Move DHCP in-band control special case into
xlate_actions().
dpif-linux: Only ask datapath to echo back results when they will be
used.
socket-util: New function get_socket_rcvbuf().
netlink-socket: New function nl_sock_transact_multiple().
dpif: New function dpif_operate() and dpif-linux implementation.
ofproto-dpif: Break send_packet_in() into two separate functions.
ofproto-dpif: Factor controller optimization out of
execute_odp_actions().
ofproto-dpif: Separate facet creation and action translation.
ofproto-dpif: Batch interacting with the dpif on flow miss
operations.
