[ Upstream commit2f09707d0c] Cong Wang noticed that the previous fix for sch_sfb accessing the queued skb after enqueueing it to a child qdisc was incomplete: the SFB enqueue function was also calling qdisc_qstats_backlog_inc() after enqueue, which reads the pkt len from the skb cb field. Fix this by also storing the skb len, and using the stored value to increment the backlog after enqueueing.

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.
