In __skb_udp_tunnel_segment(), when it's a SCTP over VxLAN/GENEVE packet and need_csum is false, which means the outer udp checksum doesn't need to be computed, csum_start and csum_offset could be used by the inner SCTP CRC CSUM for SCTP HW CRC offload. So this patch is to not remove the CRC flag from dev features when need_csum is false.
