From: HW He <hw.he@xxxxxxxxxxxx> [ Upstream commit f25caaca424703d5a0607310f0452f978f1f78d9 ] IOSM driver registers network device without setting the needs_free_netdev flag, and does NOT call free_netdev() when unregisters network device, which causes a memory leak. This patch sets needs_free_netdev to true when registers network device, which makes netdev subsystem call free_netdev() automatically after unregister_netdevice().
