In fact, I jumped the gun, and reviewing the embedded users of
netdevice, I found there are three more devices, that will need some
care before we proceed

drivers/crypto/caam/caamalg_qi2.h:

struct dpaa2_caam_priv_per_cpu {
...
struct net_device net_dev;


drivers/crypto/caam/qi.c:

struct caam_qi_pcpu_priv {
...
struct net_device net_dev;

drivers/net/ethernet/cavium/thunder/thunder_bgx.c:

struct lmac {
...
struct net_device netdev;
