2023-10-25selftests/bpf: Add netlink helper libraryDaniel Borkmann1-0/+46
Add a minimal netlink helper library for the BPF selftests. This has been taken and cut down and cleaned up from iproute2. This covers basics such as netdevice creation which we need for BPF selftests / BPF CI given iproute2 package cannot cover it yet. Stanislav Fomichev suggested that this could be replaced in future by ynl tool generated C code once it has RTNL support to create devices. Once we get to this point the BPF CI would also need to add libmnl. If no further extensions are needed, a second option could be that we remove this code again once iproute2 package has support.
