define KernelPackage/batman-adv/description
  B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
  a routing protocol for multi-hop ad-hoc mesh networks. The
  networks may be wired or wireless. See
  https://www.open-mesh.org/ for more information and user space
  tools. This package builds version $(PKG_VERSION) of the kernel
