esp4: add gso_segment for esp4 beet mode
Similar to xfrm4_tunnel/transport_gso_segment(), _gso_segment()
is added to do gso_segment for esp4 beet mode. Before calling
inet_offloads[proto]->callbacks.gso_segment, it needs to do:
- Get the upper proto from ph header to get its gso_segment
when xo->proto is IPPROTO_BEETPH.
- Add SKB_GSO_TCPV4 to gso_type if x->sel.family == AF_INET6
and the proto == IPPROTO_TCP, so that the current tcp ipv4
packet can be segmented.
- Calculate a right value for skb->transport_header and move
skb->data to the transport header position.
