Driver is currently using dma_unmap_single() with the address it passed to device for the purpose of forwarding, but the XDP transmission buffer was originally a page allocated for the rx-queue. The mapped address is likely to differ from the original mapped address due to the placement offset. This difference is going to get even bigger once we support headroom. Cache the original mapped address of the page, and use it for unmapping of the buffer when completion arrives for the XDP forwarded packet.

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.
