The following commit has been merged in the master branch: commit a6786eba9ac9d257e4f94ab8c2c0e7ace4a54ddd Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Jul 17 12:43:12 2011 +0200 batman-adv: Remove compat code for kernel versions < 2.6.29 The removal of the HAVE_NET_DEVICE_OPS in the kernel sources by David S. Miller makes it hard to implement compatibility code using compat.(c|h). Either the sources of the kernel and the external module have to diverge again or more complex workarounds have to be found. Dropping support for kernels older than 2.6.29 will remove the dead ballast of stuff older than two years. People which need it can revert 7f1b7b837c205e413a7aa078a47ec96f0c11afa7 and this patch.

The following commit has been merged in the next branch: commit a6786eba9ac9d257e4f94ab8c2c0e7ace4a54ddd Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Jul 17 12:43:12 2011 +0200 batman-adv: Remove compat code for kernel versions < 2.6.29 The removal of the HAVE_NET_DEVICE_OPS in the kernel sources by David S. Miller makes it hard to implement compatibility code using compat.(c|h). Either the sources of the kernel and the external module have to diverge again or more complex workarounds have to be found. Dropping support for kernels older than 2.6.29 will remove the dead ballast of stuff older than two years. People which need it can revert 7f1b7b837c205e413a7aa078a47ec96f0c11afa7 and this patch.
