Merge branch 'net-make-udp-tunnel-devices-support-fraglist'

Xin Long says: ==================== 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. ==================== Link: https://lore.kernel.org/r/cover.1610704037.git.lucien.xin@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
