When allocating RX or TX buffer pools, the driver needs to provide a unique mapping ID to firmware for each pool. This value is assigned using a counter which is incremented after a new pool is created. The ID can be an integer ranging from 1-255. When migrating to a device that requests a different number of queues, this value was not being reset properly. As a result, after enough migrations, the counter exceeded the upper bound and pool creation failed. This is fixed by resetting the counter to one in this 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.
