--with-l26-source has been renamed --with-linux-source. The old
names will be removed after the next release, so please update
your scripts.
+ - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and
+ datapath/linux-2.6/compat-2.6 directories.
- Feature removals:
- Dropped support for "tun_id_from_cookie" OpenFlow extension.
(Use the extensible match extensions instead.)
when invoking the configure script. For example, to build for MIPS
with Linux:
- % ./configure --with-linux=/path/to/linux-2.6 KARCH=mips
+ % ./configure --with-linux=/path/to/linux KARCH=mips
The configure script accepts a number of other options and honors
additional environment variables. For a full list, invoke
6. If you built kernel modules, you may load them with "insmod", e.g.:
- % insmod datapath/linux-2.6/openvswitch_mod.ko
+ % insmod datapath/linux/openvswitch_mod.ko
You may need to specify a full path to insmod, e.g. /sbin/insmod.
To verify that the modules have been loaded, run "/sbin/lsmod" and
2. Load the brcompat kernel module (which was built in step 1), e.g.:
- % insmod datapath/linux-2.6/brcompat_mod.ko
+ % insmod datapath/linux/brcompat_mod.ko
(openvswitch_mod.ko should already have been loaded.)

- * 16 bytes or less we avoid the reallocation.
- *
- * Unfortunately this headroom changes the DMA alignment of the resulting

- * perhaps setting it to a cacheline in size (since that will maintain
- * cacheline alignment of the DMA). It must be a power of 2.
