When dev_requeue_skb() is called with bulked skb list, only the
first skb of the list will be requeued to qdisc layer, and leak
the others without free them.
TCP is broken due to skb leak since no free skb will be considered
as still in the host queue and never be retransmitted. This happend
when dev_requeue_skb() called from qdisc_restart().
qdisc_restart
|-- dequeue_skb
|-- sch_direct_xmit()
|-- dev_requeue_skb() <-- skb may bluked
Fix dev_requeue_skb() to requeue the full bluked list. Also change
to use __skb_queue_tail() in __dev_requeue_skb() to avoid skb out
of order.
Fixes:

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
