batman-adv: Add SPDX license identifier above copyright header The "Linux kernel licensing rules" require that each file has a SPDX license identifier as first line (and sometimes as second line). The FSFE REUSE practices [1] would also require the same tags but have no restrictions on the placement in the source file. Using the "Linux kernel licensing rules" is therefore also fulfilling the FSFE REUSE practices requirements at the same time.

batman-adv: throughput meter implementation The throughput meter module is a simple, kernel-space replacement for throughtput measurements tool like iperf and netperf. It is intended to approximate TCP behaviour. It is invoked through batctl: the protocol is connection oriented, with cumulative acknowledgment and a dynamic-size sliding window. The test *can* be interrupted by batctl. A receiver side timeout avoids unlimited waitings for sender packets: after one second of inactivity, the receiver abort the ongoing test.

batman-adv: Use includes instead of fwdecls While it can be slightly beneficial for the build performance to use forward declarations instead of includes, the handling of them together with changes in the included headers makes it unnecessary complicated and fragile. Just replace them with actual includes since some parts (hwmon, ..) of the kernel even request avoidance of forward declarations and net/ is mostly not using them in *.c file.
