There is a risk that the members of the structure asix_rx_fixup_info become unsynchronised leading to the possibility of a malfunction. For example, rx->split_head was not being set to false after an error was detected so potentially could cause a malformed 32-bit Data header word to be formed. Therefore add function reset_asix_rx_fixup_info() to reset all the members of asix_rx_fixup_info so that future processing will start with known initial conditions. Also, if (skb->len != offset) becomes true then call reset_asix_rx_fixup_info() so that the processing of the next URB starts with known initial conditions. Without the call, the check does nothing which potentially could lead to a malfunction when the next URB is processed. In addition, for robustness, call reset_asix_rx_fixup_info() before every error path's "return 0". This ensures that the next URB is processed from known initial conditions.

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.
