net: dsa: rtl8366: Check validity of passed VLANs
The rtl8366_set_vlan() and rtl8366_set_pvid() get invalid VLANs tossed at it, especially VLAN0, something the hardware and driver cannot handle. Check validity and bail out like we do in the other callbacks. Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: David S.
