Keep track of usable protocols while parsing actions and matches,
rather than checking for them afterwards. This fixes silently discarded
meter and goto table instructions when not explicitly specifying the
protocol to use.

Until now, ovs-controller and the learning-switch code split responsibility
for the OpenFlow connection. This commit moves all the responsibility into
the learning-switch code.
The rationale here is twofold. First, the split itself seems odd; I think
there must have been a reason for it at one time, but I don't remember it
and don't see one anymore. Second, I intend to make the lswitch code more
stateful in upcoming commits, and it seems odd to have the lswitch manage
quite a bit of state but not the entity that that state applies to.

This better fits our general policy of adding a version number suffix
to structures and constants whose values differ from one OpenFlow
version to the next.

This commit adapts a couple of existing pieces of code to use the
new data structure. The following commit will add another user
(which is also the first use of the simap_increas() function).

Open vSwitch already handles a few different protocol variations, but it
does so in a nonuniform manner:
- OpenFlow 1.0 and NXM flow formats are distinguished using the NXFF_*
constant values from nicira-ext.h.
- The "flow_mod_table_id" feature setting is maintained in ofproto as
part of an OpenFlow connection's (ofconn's) state.
There's no way to easily communicate this state among components. It's
not much of a problem yet, but as more protocol support is added it seems
better to have an abstract, uniform way to represent protocol versions and
variants. This commit implements that by introducing a new type
"enum ofputil_protocol". Each ofputil_protocol value represents a variant
of a protocol version. Each value is a separate bit, so a single enum
can also represent a set of protocols, which is often useful as well.

Based on a patch by Jean Tourrilhes <jt@hpl.hp.com>. According to Jean,
besides increasing flexibility, this reduces normalization warnings.

ovs_queue doesn't seem very useful; it's just a singly-linked list. It's
more generally useful to use a general-purpose "struct list" for lists of
packets, so this commit adds such a member to "struct ofpbuf" and shifts
the existing users to use it.

This makes it a little easier to test Open vSwitch QoS features using
ovs-controller, by making it possible to assign queues on the basis of
input port, instead of just allowing a single queue for a whole switch.

This should make extensions easier.

A couple of people have reported that ovs-controller --with-flows is
confusing. This seems to be because it doesn't read the file with the
flows until the first connection from a switch. Then, if the file has a
syntax error, it exits.
This commit changes the behavior so that it reads the file immediately at
startup instead.

Open vSwitch has never properly supported IEEE 802.1D Spanning Tree
Protocol (STP), but it has various bits and pieces that claim to support
it. This commit deletes them, to reduce the amount of dead code in the
tree. We can always reintroduce it later if it proves to be a good idea.
Bug #1175.

Add an argument to the function to create a learning switch, which
defines default flows to be pushed down to connecting switches. It does
nothing to enforce that they remain intact. It only pushes flows on
switch connection.
|

Before, an lswitch always sent packets using OFPAT_OUTPUT, which always
uses the default OpenFlow queue. To help me debug the Open vSwitch QoS
implementation, I want to be able to send packets on other queues, so
this commit adds that feature.

This adds two command line switches to ovs-controller to:
1) Use wildcards instead of exact matches.
2) Use "normal" action instead of explicit port.
