====================
net: make udp tunnel devices support fraglist

Like GRE device, UDP tunnel devices should also support fraglist, so
that some protocol (like SCTP) HW GSO that requires NETIF_F_FRAGLIST
in the dev can work. Especially when the lower device support both
NETIF_F_GSO_UDP_TUNNEL and NETIF_F_GSO_SCTP.
