Ben Pfaff 67a603dde8 Make openflow.h SWIG-friendly. 2008-07-21 11:39:39 -07:00
Ben Pfaff e88c18152d Assert on structure sizes in openflow.h. 
This causes the build to fail if structures are not the sizes that we
expect.

Ben Pfaff b993fa9c2b Adjust OpenFlow to have same structure layout on 32- and 64-bit platforms. 
Pointed out by "Brandon Heller" <brandon.heller@gmail.com>.

Ben Pfaff 258f32a084 Respond to echo requests in OpenFlow implementations. 
Nothing yet sends such requests.  This is preparation for their
use in following commits.

Ben Pfaff 3ee68a5b11 Fix openflow.h compilation with GCC 2.95. 
Necessary because older Linux 2.4 releases will only compile with GCC 2.95.

Ben Pfaff d2552c15f3 Make table_id in OpenFlow messages 8 bits, since 255 should be enough. 
Suggested by Justin.
 2008-04-15 09:56:46 -07:00
Ben Pfaff 0a1a667973 Make duration in ofp_flow_stats a 32-bit quantity (instead of 16). 
Otherwise duration is capped at under 24 hours.

Suggested by Justin.

Justin Pettit e28564c5fa Add support for OFPP_TABLE virtual port. 2008-04-11 17:40:05 -07:00
Ben Pfaff f6cae73ec3 Implement OpenFlow statistics in switches and in dpctl. 
This has two notable omissions.  First, only at most 4k of flow statistics
are reported.  Second, aggregate statistics are not yet supported.  Both
of these are fairly easily fixable, just not fixed yet.

Ben Pfaff 60a87c9b00 Break data_hello and control_hello messages into multiple messages. 
We want to allow multiple OpenFlow connections to a switch, so that
dpctl and other management tools can also connect to a switch that
is connecte to the controller.  These tools will want to fetch the
information in the data_hello message, but currently this can only
be done by sending a control_hello message, which changes the
switch configuration state.  So breaking the hello messages up into
multiple different messages, only some of which affect configuration
state, cures the problem.

Also, clean up the kernel datapath a bit, by adding helper functions
for allocating and resizing Generic Netlink messages that encapsulate
OpenFlow messages.
