Introduce ofputil_protocol, to abstract the protocol in use on a connection.
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.

want to test the development tree, so it's better to prefer

Although we try to avoid it, some unit tests are necessarily

help with that, by preventing time from advancing from the viewpoint of
the OVS "timeval" functions except when "time/warp" explicitly advances
the current time. This should allow the unit tests that need it to become

configure: Try to extract kernel source directory from build Makefile.
OVS needs to inspect the headers in the kernel source directory at build
time. Debian keeps moving the source directory relative to the build
directory and doesn't provide an obvious way to find the source directory,
so in the past we've used some name-based heuristics to essentially guess
where it is.
This commit introduces a new heuristic that I hope will be more reliable:
extracting the source directory from the Makefile in the build directory.
In Debian's case, it looks like the Makefile generally contains a line of
the form "MAKEARGS := -C <srcdir> O=<outdir>". This commit extracts the
source directory from that line.
To avoid regressions this commit retains the older heuristics as fallbacks.

vswitchd: Always configure a default queue for QoS.
When an interface has QoS configured but no default queue (queue 0), OVS
has until now installed that QoS configuration literally, which causes all
packets destined for this default queue to be dropped. This behavior is
usually both unexpected and undesirable.
This commit changes behavior so that, when no default queue is configured,
OVS uses a default "empty" configuration for the default queue. This
behavior should be more acceptable when QoS is slightly misconfigured.
I tested that, without this patch, configuring only queue 1 causes "tc
class show" to show only queue 1 (handle 1:2) for linux-htb and linux-hfsc,
and that with this patch it shows configurations for both queue 0 (handle
1:1) and queue 1.
