0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * module. It is currently in bpf, rather than mac (like ipnet_bpf)
0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * because of the mac/dls split. The bpf driver needs to know when
0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * interfaces appear and disappear and the best place for that is in
0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * dls. Unfortunately all of the other functions used here are found
0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * in the mac module, making it seem ill suited to being at home in
0a0e9771ca0211c15f3ac4466b661c145feeb9e4Darren Reed * dls. Similarly it has even less purpose being in mac as it is
