This only looks for instances that need free_netdev() call, ie. struct net_device::needs_free_netdev == true.I think we may need to worry about more kernel versions than just 4.12 here, since this stuff is getting backported, and then it would cause double-frees. I'm also considering simply removing the priv_destructor entirely from mac80211, but I guess this would still apply to other drivers.
For current backports the only other driver is brcmfmac. So you don't need it in mac80211? Does that mean you move stuff to .ndo_uninit()?
