This patch implements ice_start_xmit (the handler for ndo_start_xmit) and related functions. ice_start_xmit ultimately calls ice_tx_map, where the Tx descriptor is built and posted to the hardware by bumping the ring tail. This patch also implements ice_napi_poll, which is invoked when there's an interrupt on the VSI's queues. The interrupt can be due to either a completed Tx or an Rx event. In case of a completed Tx/Rx event, resources are reclaimed. Additionally, in case of an Rx event, the skb is fetched and passed up to the network stack.

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.
