To enable SNAT, run configure with the "--enable-snat" flag. This has
only been tested with the 2.6.23 kernel...more diverse testing will follow.
Documentation and a cleaner build setup will also be in a future check-in.
Allow vendors to define their own actions. Actions were originally fixed-
length, which was a bit constraining. Actions now contain a length field,
which gives them more flexibility.
The tests haven't been seeing much love and are suffering from bit-rot at
this point. We're removing them, since we have other ways to test at
this point.
To report on link status and whether a port is administratively enabled or
disabled, the reference switches poll. This change uses the Linux kernel's
device notification system, so that polling isn't necessary.
The new OFPT_ECHO_REQUEST and OFPT_ECHO_REPLY OpenFlow messages
have the same functionality and are more general (in that they
are not Netlink-specific).
We need object files to depend on the build directories, so that the
build directories get created before we try to output files into them.
But making them depend directly on the build directories means that
whenever a build directory changes (including any change to the set of
files inside it) all the source files get recompiled. So, instead, make
them depend on dummy files inside the directories, which will only get
modified if someone does it intentionally.
The new build system supports using a build tree separate from the
source tree, which makes it easier to build for multiple targets
using a single source tree. It also factors out the means for specifying
the modules to be built and the source files that comprise those
modules into simple files named Modules.mk. This is intended to
make it easier to add support for separate hardware table modules in
an upcoming commit.
