[PATCH net-next v4 09/12] net: ethernet: aquantia: Call netdev_register after all initialized.

[Pavel Belous]

From: Pavel Belous <pavel.bel...@aquantia.com>

netdev_register should be called when everything is initialized.
Also we should use net_device->reg_state field instead own
"is_ndev_registered" flag to avoid any race.
