Liubin Shu 3a39a12ad3 net: hns: fix KASAN: use-after-free in hns_nic_net_xmit_hw()
This patch is trying to fix the issue due to:
[27237.844750] BUG: KASAN: use-after-free in hns_nic_net_xmit_hw+0x708/0xa18[hns_enet_drv]

After hnae_queue_xmit() in hns_nic_net_xmit_hw(), can be
interrupted by interruptions, and than call hns_nic_tx_poll_one()
to handle the new packets, and free the skb. So, when turn back to
hns_nic_net_xmit_hw(), calling skb->len will cause use-after-free.

This patch update tx ring statistics in hns_nic_tx_poll_one() to
fix the bug.

README

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.
