[ Upstream commit296d5b5416] For every RX packet, the driver replenishes all buffers used for that packet and puts them back into the RX ring and RX aggregation ring. In one code path where the RX packet has one RX buffer and one or more aggregation buffers, we missed recycling the aggregation buffer(s) if we are unable to allocate a new SKB buffer. This leads to the aggregation ring slowly running out of buffers over time. Fix it by properly recycling the aggregation buffers. Fixes:c0c050c58d("bnxt_en: New Broadcom ethernet driver.")

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.
