Xin Long c7a42eb492 net: ipv6: fix listify ip6_rcv_finish in case of forwarding We need a similar fix for ipv6 as Commit `0761680d52` ("net: ipv4: fix listify ip_rcv_finish in case of forwarding") does for ipv4. This issue can be reprocuded by syzbot since Commit `323ebb61e3` ("net: use listified RX for handling GRO_NORMAL skbs") on net-next. The call trace was: kernel BUG at include/linux/skbuff.h:2225!

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.
