In aq_ring_rx_clean(), if buff->is_eop is not set AND buff->len < AQ_CFG_RX_HDR_SIZE, then hdr_len remains equal to buff->len and skb_add_rx_frag(xxx, *0*, ...) is not called. The loop following this code starts calling skb_add_rx_frag() starting with i=1 and thus frag[0] is never initialized. Since i is initialized to zero at the top of the primary loop, we can just reference and post-increment i instead of hardcoding the 0 when calling skb_add_rx_frag() the first time.

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.
