net: ethtool: add VxLAN to the NFC API 

driver inclusion
category:feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I61CGU



----------------------------------------------------------------------

To support for steering VxLAN flows using the ethtool NFC interface, this
patch adds flow specifications for vxlan4(VxLAN with inner IPv4) and vxlan6
(VxLAN with inner IPv6).
