From: Nora Schiffer <redacted> batman-adv is using netdev notifiers to create a hard_iface struct for every Ethernet-like netdev in the system. These hardifs are tracked in a global linked list, which results in a few performance issues: Lookups in this list are O(n) in the total number of netdevs. As a hardif is looked up when a netdev is removed, this also takes O(n) in the number of netdevs, and removing n netdevs may take O(n^2). This slowdown will always happen when the batman-adv module is loaded, no mesh needs to be active. [...]
