gro list uses skb_shinfo(skb)->frag_list to link two skb together, and NAPI_GRO_CB(p)->last->next is used when there are more skb, see skb_gro_receive_list(). gso expects that each segmented skb is linked together using skb->next, so only the first skb->next need to set to skb_shinfo(skb)-> frag_list when doing gso list segment. It is the same reason that nskb->next does not need to be set to list_skb before goto the error handling, because nskb->next already pointers to list_skb. And nskb is also the last skb at the end of loop, so remove tail variable and use nskb instead. Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> Signed-off-by: David S.

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.
