Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit a98694018f7909f126bb425b06acb591ba608909 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Mar 20 14:00:15 2016 +0100 batman-adv: Drop support for Linux < 3.2 The Linux Kernel 2.6.32 reached its end of life [1] after over 6 years. Instead it is recommended to use at least kernel 3.2 which is also already over 3 years old. All older kernels (v2.6.29 - v3.1) should therefore be dropped to reduce the support overhead.
