Update routing packages (batman-adv v2016.5)
Also remove our own no_rebroadcast patch, as batman-adv v2016.5 now has a more sophisticated rebroadcast suppression that should work automatically in the most relevant cases.

|
||||
+MIME-Version: 1.0
|
||||
+Content-Type: text/plain; charset=UTF-8
|
||||
+Content-Transfer-Encoding: 8bit
|
||||
+
|
||||
+This patch introduces a new sysfs option named "no_rebroadcast" on
|
||||
+a per hard interface basis. It allows manually enabling a split-horizon
|
||||
+like behaviour for the layer 2 multicast payload frames, in that
|
||||
+incoming multicast payload frames on such a hard interface are only
|
||||
+being rebroadcasted on all interfaces except the incoming one instead
|
||||
+of being rebroadcasted on all interfaces.
|
||||
+
|
||||
+Such an option should only be enabled if you are certain that these
|
||||
+rebroadcasts are unnecessary. This is usually the case for instance
|
||||
+for point-to-point wifi longshots or wired links.
|
||||
+
|
||||
+This option can especially safe a significant amount of upload overhead
|
||||
+if the neighbourhood on a link is rather large, for instance in some
|
||||
+transitive, symmetric VPN configurations.
|
||||
+
|
||||
+Using this option wrongly will break your mesh network, use this option
|
||||
+wisely and at your own risk!

Subject: batman-adv: use kernel-specific PKG_BUILD_DIR
|
||||
|
||||
The batman-adv Makefile set a PKG_BUILD_DIR outside of KERNEL_BUILD_DIR;
|
||||
this could lead to batman-adv not being rebuilt when switching targets and
|
||||
thus kernel configurations. This resulted in ABI mismatches and
|
||||
occasionally broke the build with messages like the following:
|
||||
|
||||
Package kmod-batman-adv is missing dependencies for the following libraries:
|
||||
crc16.ko
|
||||
|
||||
Instead of setting a better PKG_BUILD_DIR ourselves, we can just remove
|
||||
the explicit PKG_BUILD_DIR definition and include kernel.mk before
|
||||
package.mk to get the default definition used by other kernel module
|
||||
packages.
