In order to support build_skb with jumbo frames it will be necessary to use 3K buffers for the Rx path with 8K pages backing them. This is needed on architectures that implement 4K pages because we can't support 2K buffers plus padding in a 4K page. In the case of systems that support page sizes larger than 4K the 3K attribute will only be applied to FCoE as we can fall back to using just 2K buffers and adding the padding.

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.
