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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
