[Linux-stable-mirror] Patch "sh_eth: fix SH7757 GEther initialization" has been added to the 4.9-stable tree

Shimoda-san tried to solve that adding the 'needs_init' member to the 'struct sh_eth_plat_data', however the platform code still never sets this flag. I think that we can infer this information from the 'devno' variable (set to 'platform_device::id') and reset/init the Ether controller pair only for an even 'devno'; therefore 'sh_eth_plat_data::needs_init' can be removed...

Also, VLAN 0 is probably not a valid number and it is kinda "reserved" for HW accelerating devices, but it is probably too late to reject it from creation even if makes sense. Instead, just remove the check in unregister_vlan_dev().
