During the teardown of a RX channel, because there is only one completion queue available for RX channel, descriptor of another channel may be popped which will cause 2 warnings: - the first one because we popped a wrong descriptor (neither the channel's descriptor, nor the teardown descriptor). - the second one happen during the teardown of another channel, because we can't find the channel descriptor (that is, the one that caused the first warning). To avoid that, use one free queue instead of a transmit completion queue. Note that fix doesn't fix all the teardown warnings: I still get some when I run some corner case.

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.
