[IPv6] Don't generate temporary for TUN devices
Userland layer-2 tunneling devices allocated through the TUNTAP driver
(drivers/net/tun.c) have a type of ARPHRD_NONE, and have no link-layer
address. The kernel complains at regular interval when IPv6 Privacy
extension are enabled because it can't find an hardware address :
Dec 29 11:02:04 auguste kernel: __ipv6_regen_rndid(idev=cb3e0c00):
cannot get EUI64 identifier; use random bytes.
IPv6 Privacy extensions should probably be disabled on that sort of
device. They won't work anyway. If userland wants a more usual
Ethernet-ish interface with usual IPv6 autoconfiguration, it will use a
TAP device with an emulated link-layer and a random hardware address
rather than a TUN device.
As far as I could fine, TUN virtual device from TUNTAP is the very only
sort of device using ARPHRD_NONE as kernel device type.
