In current code, xfrm_bundle_create() always uses the matched
SA's family type to look up a xfrm child route for the skb.
The route returned by xfrm_dst_lookup() will eventually be
used in xfrm_output_resume() (skb_dst(skb)->ops->local_out()).
If packet offload is used, the above behavior can lead to
calling ip_local_out() for an IPv6 packet or calling
ip6_local_out() for an IPv4 packet, which is likely to fail.
This change fixes the behavior by checking if the matched SA
has packet offload enabled. If not, keep the same behavior;
if yes, use the matched SP's family type for the lookup.
Test: verified IPv6-in-IPv4 packets on Android device with
IPsec packet offload enabled

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.
