napi_alloc_skb() doesn't need to disable IRQs during the allocation, and thus may save us a few cycles. Doing so requires a small fix-up in the HiperTransport path, which currently assumes a fixed NET_SKB_PAD headroom padding. napi_alloc_skb() adds an additional NET_IP_ALIGN padding, so use the proper helper for setting up the mac_header offset. Use this opportunity to convert the non-NAPI path to netdev_alloc_skb(), which means that skb->dev is now always set-up during allocation and doesn't need to be assigned manually.

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.
