Most protocol-specific pointers in struct net_device are under a respective ifdef. Wireless is the notable exception. Since there's a sizable number of custom-built kernels for datacenter workloads which don't build wireless it seems reasonable to ifdefy those pointers as well. While at it move IPv4 and IPv6 pointers up, those are special for obvious reasons. Signed-off-by: Jakub Kicinski <kuba@xxxxxxxxxx>
Could not we move to an union of pointers in the future since in many cases a network device can only have one of those pointers at any given time?
